Abstract

A toner cartridge comprises a toner container which contains toner, a driving member which rotationally drives a conveying member, an agitating member which agitates a toner in the toner container while being rotated, a driven member which rotates in association with the driving member which is for rotationally driving the agitating member, and a rotational body which rotates according to rotation of the driven member, has a plurality of slits in rotational circumference for identifying a type of the toner cartridge, and has 1/K or more of the slits when a ratio of a rotational speed R1 (rad/s) of the driving member and a rotational speed R2 (rad/s) of the driven member is K=R2/R1.

First claim

What is claimed is:

1. A toner cartridge comprising:
a container configured to contain toner;
a lid body provided on the container, a part of the lid body including a protrusion having an oblique surface facing inside of the container, the protrusion abutting the container; and
a rib provided in the part above the protrusion.

2. The toner cartridge according to claim 1 , wherein the lid body has a rectangular plate shape.

3. The toner cartridge according to claim 1 , further comprising:
an agitating member configured to agitate the toner in the container.

4. The toner cartridge according to claim 1 , further comprising:
a toner supplying opening formed in the container.

5. The toner cartridge according to claim 4 , further comprising:
a conveying member configured to convey the toner toward the toner supplying opening.

6. The toner cartridge according to claim 1 , further comprising:
another rib in the part above the protrusion.

7. The toner cartridge according to claim 6 , wherein the rib and said another rib are parallel with each other.

8. The toner cartridge according to claim 1 , wherein the protrusion is located at an upper edge of the container.

9. The toner cartridge according to claim 1 , wherein the container has a U-shaped cross section.

10. The toner cartridge according to claim 9 , wherein the protrusion is located at an upper edge of the U-shaped cross section of the container.

11. The toner cartridge according to claim 1 , wherein the protrusion has a cross section of a triangle shape.

12. The toner cartridge according to claim 1 , wherein the protrusion has a cross section of a triangle shape formed by first and second lines crossing at a right angle and a third line determined by the first and second lines.

13. The toner cartridge according to claim 12 , wherein the second line abuts the container.

14. The toner cartridge according to claim 12 , wherein the second line abuts an inner wall of the container.

15. The toner cartridge according to claim 12 , wherein a surface including the second line and a line extending along a longitudinal direction of the lid body abuts the container.

16. The toner cartridge according to claim 12 , wherein a surface including the second line and a line extending along a longitudinal direction of the lid body abuts an inner wall of the container.

17. The toner cartridge according to claim 1 , wherein the protrusion has a cross section of a triangle shape formed by:
a first line having a first length from a connection of the lid body and the container,
a second line crossing the first line at a right angle and having a second length from the connection toward a bottom of the container, and
a third line determined by the first line and the second line.

18. The toner cartridge according to claim 17 , wherein the first line is shorter than the second line.

19. The toner cartridge according to claim 1 , wherein the protrusion abuts an inner wall of the container.

20. The toner cartridge according to claim 1 , wherein the rib extends in a plane crossing a longitudinal direction of the lid body.
