Abstract
A cartridge includes a coupling member for receiving a rotational force for rotating a developing roller. The cartridge also includes a cylinder including an accommodating portion accommodating at least a part of the coupling member, the cylinder being configured to transmit the rotational force from the coupling member to the developing roller. The cartridge further includes a frame including a bearing configured to rotatably support the cylinder and a regulating wall capable of regulating movement of the coupling member by contacting the coupling member. The bearing encompasses the regulating wall as seen along a rotational axis of the cylinder.
