Cleaning device and image forming apparatus
View Patent ↗A cleaning device includes a cleaning device body including a cleaning member, the cleaning member being in contact with a surface of an image carrier so as to remove developer retained on the surface of the image carrier; and a fixing member that fixes an end of the cleaning device body in a longitudinal direction to a side surface of a frame that supports the image carrier and corresponds to the end of the cleaning device body in the longitudinal direction.
1. An image forming apparatus comprising:
an image carrier that retains developer;
a frame that supports the image carrier and has a fixing hole; and
a cleaning device that cleans the image carrier by removing the developer retained by the image carrier from the image carrier,
the cleaning device includes:
a cleaning device body including a cleaning member, a fitting hole, and a transporting member, the cleaning member being in contact with a surface of the image carrier so as to remove the developer retained on the surface of the image carrier and the transporting member transports the developer removed from the image carrier by the cleaning member and is inserted into the fitting hole, and
a fixing member that fixes an end of the cleaning device body in a longitudinal direction to a side surface of a frame that supports the image carrier and corresponds to the end of the cleaning device body in the longitudinal direction,
wherein the fixing member includes a shaft bearing portion that supports the transporting member in a rotatable manner, and
wherein a part of the fixing member is inserted into the fixing hole from a direction parallel to a rotational axis of the transporting member and fixed to the frame.
2. The image forming apparatus according to claim 1 , further comprising:
a fixing device that fixes developer that has been transferred onto a recording medium to the recording medium,
wherein the cleaning device body is disposed in a space provided between the fixing device and the image carrier.
3. The image forming apparatus according to claim 2 , further comprising:
a backing member provided on another surface of the image carrier and serving as a backing for the cleaning member, the backing member being supported by the frame.
4. The image forming apparatus according to claim 3 , wherein the fixing member functions as a connection portion that provides a connection to another section for transporting the developer transported by the transporting member to the another section.
5. The image forming apparatus according to claim 2 , wherein the fixing member functions as a connection portion that provides a connection to another section for transporting the developer transported by the transporting member to the another section.
6. The image forming apparatus according to claim 1 ,
wherein the fixing member has a second shaft bearing portion that rotatably supports a backing member,
wherein the shaft bearing portion and the second shaft bearing portion are linearly provided, such that the fixing member fixes the cleaning device body and the backing member as a whole to respective positions.
7. The image forming apparatus according to claim 6 , wherein the fixing member functions as a connection portion that provides a connection to another section for transporting the developer transported by the transporting member to the another section.
8. The image forming apparatus according to claim 1 , further comprising:
a backing member provided on another surface of the image carrier and serving as a backing for the cleaning member, the backing member being supported by the frame.
9. The image forming apparatus according to claim 8 , wherein the fixing member functions as a connection portion that provides a connection to another section for transporting the developer transported by the transporting member to the another section.
10. The image forming apparatus according to claim 1 , wherein the fixing member functions as a connection portion that provides a connection to another section for transporting the developer transported by the transporting member to the another section.
11. The image forming apparatus according to claim 1 , wherein the cleaning member is located below the fixing member.
12. The image forming apparatus according to claim 1 , wherein the cleaning member is fixed to the cleaning device body.
13. The image forming apparatus according to claim 1 , wherein the fixing member contacts the cleaning member at an inner side of the outer surface of the frame in the direction parallel to the rotational axis of the transporting member.
14. A cleaning method with which an image carrier is cleaned by using a cleaning device body, the cleaning method comprising:
bringing a cleaning member into contact with a surface of an image carrier,
removing developer retained on a surface of the image carrier while coming in contact with the surface; and
transporting the developer removed from the image carrier with a transporting member;
inserting a transporting member into a fitting hole;
fixing an end of the cleaning device body in a longitudinal direction to a side surface of a frame that supports the image carrier and corresponds to the end of the cleaning device body in the longitudinal direction,
wherein the fixing member includes a shaft bearing portion that rotatably supports the transporting member, and
wherein a part of the fixing member is inserted into a fixing hole of the frame from a direction parallel to a rotational axis of the transporting member and fixed to the frame.
15. An image forming apparatus comprising:
an image carrier that retains developer;
a frame that supports the image carrier and has a fixing hole; and
a cleaning device that cleans the image carrier by removing the developer retained by the image carrier from the image carrier,
the cleaning device includes:
a cleaning device body including a cleaning member, the cleaning member being in contact with a surface of an image carrier so as to remove developer retained on the surface of the image carrier; and
a fixing member that fixes an end of the cleaning device body in a longitudinal direction to a side surface of a frame that supports the image carrier and corresponds to the end of the cleaning device body in the longitudinal direction, and
wherein the fixing member fixes the cleaning device body and the backing member so that the cleaning device body and the backing member do not slide with respect to the fixing member,
wherein a part of the fixing member is inserted into the fixing hole from a direction parallel to a rotational axis of the transporting member and fixed to the frame.
16. The image forming apparatus according to claim 15 , wherein the cleaning member is located below the fixing member.
