Developing cartridge having coupling and developing roller
First Claim
1. A cartridge comprising:
- a coupling rotatable about a first axis extending in a first direction;
a coupling gear rotatable with the coupling about the first axis;
a developing roller including a developing roller shaft extending in the first direction, the developing roller being rotatable about a second axis extending in the first direction and the developing roller shaft including a first end portion and a second end portion separated from the first end portion in the first direction;
a developing gear meshing with the coupling gear, the developing gear being mounted to the first end portion of the developing roller shaft, and the developing gear being rotatable with the developing roller shaft about the second axis;
an agitator including an agitator shaft extending in the first direction, the agitator shaft including a first end portion and a second end portion separated from the first end portion of the agitator shaft in the first direction, the agitator being rotatable with the agitator shaft about a third axis extending in the first direction;
a first gear mounted to the first end portion of the agitator shaft and rotatable with the agitator shaft;
a second gear mounted to the second end portion of the agitator shaft and rotatable with the agitator shaft; and
an idle gear meshing with the coupling gear and the first gear.

Abstract
In a cartridge, a housing has a developer accommodating portion and includes a first side wall and a second side wall. A coupling member is disposed at a position opposite to the developer accommodating portion with respect to the first side wall. A detection body is disposed at a position opposite to the developer accommodating portion with respect to the second side wall. A first driving force transmission member is positioned at the same side with the coupling member with respect to the first side wall, and transmits driving force from the coupling member to a rotating member. A second driving force transmission member is positioned at the same side with the detection body with respect to the second side wall, and transmits driving force from the rotating member to the detection body.
