Abstract

Official abstract text for this publication.

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

Opening claim text (preview).

What is claimed is: 1. A toner cartridge comprising: a container configured to contain toner, the container having a longitudinal direction and a width direction which is perpendicular to the longitudinal direction; and 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 along with the width direction. 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 , wherein the protrusion has a straight part and the straight part abuts the container. 7. The toner cartridge according to claim 1 , wherein the protrusion is located at an upper edge of the container. 8. The toner cartridge according to claim 1 , wherein the container has a U-shaped cross section. 9. The toner cartridge according to claim 8 , wherein the protrusion is located at an upper edge of the U-shaped cross section of the container. 10. The toner cartridge according to claim 1 , wherein a front side of the protrusion abuts the container. 11. The toner cartridge according to claim 10 , wherein the front side of the protrusion abuts an inner side of a front wall of the container. 12. The toner cartridge according to claim 10 , wherein the lid body has a flat part connecting to the protrusion at the front side.
