Abstract

A protection member for attachment to a replacement component before the replacement component is inserted into a body of an apparatus, to protect the replacement component, the replacement component being to be inserted into the body of the apparatus so as to act as a part of the apparatus, the protection member includes: a contact portion configured to come into contact with the body of the apparatus at a stage where a portion of the replacement component on a front side in an insertion direction is inserted into the body of the apparatus while the protection member is attached to the replacement component, in which the protection member is removed at the stage where the portion is inserted into the body of the apparatus, so as to allow further insertion of the replacement component.

Claims (67)

1. A protection member comprising:

a contact protrusion configured to contact an image forming apparatus if a portion of a replacement component, which is attached to the contact protrusion, is inserted into a body of the image forming apparatus in an insertion direction,

wherein the contact protrusion is provided at a front end of the protection member in the insertion direction,

wherein the contact protrusion protrudes primarily in the insertion direction,

wherein the protection member is removable after the portion is inserted into the body, so as to allow further insertion of the replacement component, and

wherein the protection member comprises:

one or more windows arranged in the insertion direction.

2. The protection member according to claim 1 , wherein the protection member is configured to not cover the contact protrusion and to leave the contact protrusion exposed.

3. The protection member according to claim 2 , further comprising:

a handle disposed on a rear side of the protection member in the insertion direction, the handle being configured to receive a removal operation.

4. The protection member according to claim 3 , wherein the replacement component comprises a plurality of unit parts extending in the insertion direction, the unit parts being arranged in a width direction intersecting the insertion direction, and

wherein the one or more windows is a plurality of windows,

wherein the protection member comprises:

a protrusion on a surface of a window frame that separates adjacent windows, wherein the surface of the window frame faces the replacement component, and wherein the protrusion is between adjacent ones of the unit parts.

5. A replacement component comprising:

the protection member according to claim 4 ,

wherein the replacement component is configured to be inserted into the body so as to act as a part of the image forming apparatus and to allow the image forming apparatus to operate to form a toner image, and transfer and fix the toner image on a sheet.

6. A replacement component comprising:

the protection member according to claim 3 ,

wherein the replacement component is configured to be inserted into the body so as to act as a part of the image forming apparatus and to allow the image forming apparatus to operate to form a toner image, and transfer and fix the toner image on a sheet.

7. The protection member according to claim 2 , wherein the replacement component comprises a plurality of unit parts extending in the insertion direction, the unit parts being arranged in a width direction intersecting the insertion direction, and

wherein the one or more windows is a plurality of windows,

wherein the protection member comprises:

a protrusion on a surface of a window frame that separates adjacent windows, wherein the surface of the window frame faces the replacement component, and wherein the protrusion is between adjacent ones of the unit parts.

8. A replacement component comprising:

the protection member according to claim 7 ,

wherein the replacement component is configured to be inserted into the body so as to act as a part of the image forming apparatus and to allow the image forming apparatus to operate to form a toner image, and transfer and fix the toner image on a sheet.

9. A replacement component comprising:

the protection member according to claim 2 ,

wherein the replacement component is configured to be inserted into the image forming apparatus so as to act as a part of the image forming apparatus and allow the image forming apparatus to form a toner image, and transfer and fix the toner image on a sheet.

10. The protection member according to claim 1 , further comprising:

a handle disposed on a rear side of the protection member in the insertion direction, the handle being configured to receive a removal operation.

11. The protection member according to claim 10 , wherein the replacement component comprises a plurality of unit parts extending in the insertion direction, the unit parts being arranged in a width direction intersecting the insertion direction, and

wherein the one or more windows is a plurality of windows,

wherein the protection member comprises:

a protrusion on a surface of a window frame that separates adjacent windows, wherein the surface of the window frame faces the replacement component, and wherein the protrusion is between adjacent ones of the unit parts.

12. A replacement component comprising:

the protection member according to claim 11 ,

wherein the replacement component is configured to be inserted into the body so as to act as a part of the image forming apparatus and to allow the image forming apparatus to operate to form a toner image, and transfer and fix the toner image on a sheet.

13. A replacement component comprising:

the protection member according to claim 10 ,

wherein the replacement component is configured to be inserted into the body so as to act as a part of the image forming apparatus and to allow the image forming apparatus to operate to form a toner image, and transfer and fix the toner image on a sheet.

14. The protection member according to claim 1 , wherein the replacement component comprises a plurality of unit parts extending in the insertion direction, the unit parts being arranged in a width direction intersecting the insertion direction, and

wherein the one or more windows is a plurality of windows,

wherein the protection member comprises:

a protrusion on a surface of a window frame that separates adjacent windows, wherein the surface of the window frame faces the replacement component, and wherein the protrusion is between adjacent ones of the unit parts.

15. A replacement component comprising:

the protection member according to claim 14 ,

wherein the replacement component is configured to be inserted into the body so as to act as a part of the image forming apparatus and to allow the image forming apparatus to operate to form a toner image, and transfer and fix the toner image on a sheet.

16. A replacement component comprising:

the protection member according to claim 1 ,

wherein the replacement component is configured to be inserted into the image forming apparatus so as to act as a part of the image forming apparatus and allow the image forming apparatus to form a toner image, and transfer and fix the toner image on a sheet.

17. The replacement component according to claim 16 , wherein the replacement component is a component comprising an image carrier configured to be subject to the formation of the toner image and temporarily carry the toner image until the toner image is transferred to a transfer body.

18. The replacement component according to claim 17 , wherein the replacement component is a component in which a plurality of image carriers are arranged in a width direction intersecting the insertion direction, and

wherein the protection member is a component that extends over the plurality of arranged image carriers.

19. An image forming apparatus comprising:

a body; and

a replacement component configured to be inserted into the body so as to act as a part of the image forming apparatus and allow the image forming apparatus to operate to form a toner image, and transfer and fix the toner image on a sheet,

wherein the body comprises:
