Toner container and image forming apparatus
A toner container and an image forming apparatus are disclosed. The toner container includes a guiding member formed at a part surrounding a toner outlet to be protruded from a circumferential surface of the toner container for guiding an opening or closing operation of a shutter member in a circumferential direction of the toner container. The image forming apparatus includes an image forming apparatus main body. The image forming apparatus main body includes a main body side shutter for opening or closing a toner supplying opening to be connected to the toner outlet. When the shutter member is opened, an end surface of the guiding member pushes the main body side shutter together with the opening operation of the shutter member, and the toner supplying opening is opened and is connected to the toner outlet.
1. A toner container for use with an image forming apparatus, the toner container comprising:
a toner storing section having a cylindrical shape and a length;
a toner outlet at a circumferential surface of the toner container for discharging toner in the toner container to a toner supply opening of the image forming apparatus;
a shutter member at a circumferential surface of the toner container for opening or closing the toner outlet due to rotation of the toner container in a state where the toner container is attached to the image forming apparatus; and
a brim section in the shutter member and extending in a direction along the length of the toner container, the brim section being at an end of the toner container, when the shutter member opens the toner outlet,
wherein the brim section covers an opening of a toner receiving section of the image forming apparatus when the toner container is attached to the image forming apparatus; and
wherein the toner receiving section of the image forming apparatus receives toner dropped from a surface of the shutter member when the toner container is detached from the image forming apparatus.
2. The toner container as claimed in claim 1 , wherein the shutter member has a protrusion unit in the brim section, for preventing the shutter member from being assembled with the toner container in a wrong direction.
3. The toner container as claimed in claim 1 , further comprising:
a cap section which is secured to the image forming apparatus when the toner container is attached to the image forming apparatus; and
a container main body to be connected to the cap section for carrying the toner by being rotated in a predetermined direction when a driving force is received from the image forming apparatus; wherein
the cap section includes the toner outlet, the shutter member, and a guiding member.
4. The toner container as claimed in claim 1 , further comprising:
a carrying member for carrying the toner in the toner storing section by being rotated in a predetermined direction when a driving force is received from the image forming apparatus.
5. The toner container as claimed in claim 1 , wherein:
the shutter member has two protrusions facing a circumferential surface of the toner container at positions separated from each other.
6. The toner container as claimed in claim 5 , wherein:
the two protrusions of the shutter member are at least at an end of the shutter member in the direction along the length of the toner container.
7. The toner container as claimed in claim 1 , wherein:
a restricting portion of the shutter member contacts with a protrusion provided on the circumferential surface of the toner container, and restricts a movement of the shutter member, and releases the movement when a force of a predetermined amount or more is applied to the shutter member.
8. The toner container as claimed in claim 1 , wherein the toner container is to be inserted into an image forming apparatus with a side at which a toner outlet is provided inserted after another side opposite thereto.
9. The toner container as claimed in claim 8 , wherein the toner container becomes attached by rotating clockwise after the insertion.
10. The toner container as claimed in claim 1 , wherein the toner container is in communication with a toner supplying opening of the image forming apparatus when the toner container is attached to the image forming apparatus and the toner outlet is facing downward in a vertical direction.
11. An image forming apparatus comprising:
the toner container as claimed in claim 1 .
12. The toner container as claimed in claim 1 , wherein the toner supply opening is different from the opening of the toner receiving section.
13. The toner container as claimed in claim 1 , further comprising:
a handle at the end of the toner container at which the brim section is disposed.
14. The toner container as claimed in claim 13 , wherein:
the handle is attached to the toner container at a surface perpendicular to the length of the toner storing section.
15. The toner container as claimed in claim 1 , wherein:
the brim section extends beyond the end of the toner container.
16. The toner container as claimed in claim 15 , wherein:
the brim section extends beyond the end of the toner container when the shutter member is both opening and closing the toner outlet.
17. The toner container as claimed in claim 1 , wherein:
the shutter member moves in a path of an arc along the circumferential surface of the toner container, to open and close the toner outlet.
