Abstract

A toner container includes a cylindrical container body, having a first opening in a first end thereof and a notch in a circumferential surface thereof continuous with the first opening in the first end, a flange member to engage the first opening and the notch in the container body and having a toner outlet therein through which toner in the container body is discharged, a shutter member disposed on the outer circumferential surface of the container body, a conveyance member, rotatably installed inside the container body to convey the toner from a second end of the container body opposite the first end to the toner outlet in the flange member, and a recessed portion in the container body that projects inward into the interior of the toner container 5 mm or less from an inner surface of the container body.

First claim

What is claimed is:

1. A toner container, comprising:
a container body;
a toner outlet through which toner in the container body is discharged in a direction perpendicular to a longitudinal direction of the toner container;
a conveyor to convey the toner within the container body towards the toner outlet;
a toner inlet disposed at an end face perpendicular to the longitudinal direction of the container body;
a memory on the toner container; and
a coupling to receive a driving force, the coupling to transmit the driving force to the conveyor,
wherein the toner outlet, the toner inlet, and the memory are disposed on a first side in the longitudinal direction of the toner container, and the coupling is disposed on a second side, which is opposite to the first side, in the longitudinal direction of the toner container.

2. The toner container according to claim 1 , further comprising:
a handle outwardly extending from the toner container,
wherein the handle is disposed on the first side of the toner container in the longitudinal direction of the toner container.

3. The toner container according to claim 2 , wherein:
a rotational position of the handle is fixed relative to a position of the toner outlet.

4. The toner container according to claim 2 , further comprising:
a seal to seal the toner inlet.

5. The toner container according to claim 4 , wherein:
the handle extends across the toner inlet.

6. The toner container according to claim 4 , further comprising:
an identifying protrusion to prevent an installation of the toner container in a place in an image forming apparatus which is structured to accept a container which includes toner of a different color than a color of toner that is contained in the toner container,
wherein the identifying protrusion is disposed on the first side of the toner container in the longitudinal direction of the toner container.

7. The toner container according to claim 6 , further comprising:
a guide rib having a length parallel to the longitudinal direction of the toner container, the guide rib to guide the toner container during installation of the toner container in the image forming apparatus,
wherein the guide rib is disposed on the first side of the toner container in the longitudinal direction of the toner container.

8. The toner container according to claim 1 , further comprising:
a seal to seal the toner inlet.

9. The toner container according to claim 1 , further comprising:
an identifying protrusion to prevent an installation of the toner container in a place in an image forming apparatus which is structured to accept a container which includes toner of a different color than a color of toner that is contained in the toner container,
wherein the identifying protrusion is disposed on the first side of the toner container in the longitudinal direction of the toner container.

10. The toner container according to claim 1 , further comprising:
a guide rib having a length parallel to the longitudinal direction of the toner container, the guide rib to guide the toner container during installation of the toner container in the image forming apparatus,
wherein the guide rib is disposed on the first side of the toner container in the longitudinal direction of the toner container.

11. The toner container according to claim 1 , wherein:
the conveyor is formed separately from the container body.

12. The toner container according to claim 11 , wherein:
the conveyor is rotatably disposed inside the container body and extends along the longitudinal direction of the toner container.

13. The toner container according to claim 1 , wherein:
the coupling is formed separately from the container body.

14. The toner container according to claim 1 , further comprising:
a shutter to open and close the toner outlet during installation and removal of the toner container in and from an image forming apparatus.

15. The toner container according to claim 1 , further comprising:
toner within the container body.

16. The toner container according to claim 15 , further comprising:
carrier within the container body.

17. The toner container according to claim 1 , wherein the container body comprises a cylindrical shape.

18. The toner container according to claim 1 , wherein:
the toner container is for use in an image forming apparatus, and
the coupling is to receive a driving force from the image forming apparatus.
