A cartridge includes a developing roller and a coupling member for receiving a rotational force for rotating the developing roller. The cartridge also includes a frame having 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. A spring presses the coupling member to contact the regulating wall, and the bearing encompasses the regulating wall as seen along a rotational axis of the cylinder.
