Process cartridge with a coupling member having a movable force receiving portion

A process cartridge comprising:

• a photosensitive drum;
• a rotatable developing roller for developing an electrostatic latent image formed on the photosensitive drum;
• a coupling member including a driving force receiving portion for receiving a driving force to be transmitted to the developing roller, wherein the driving force receiving portion is movable relative to the developing roller in a direction crossing an axis of the developing roller;
• an urging member for urging the driving force receiving portion in the direction crossing the axis of the developing roller;
• a supporting portion for rotatably supporting the driving force receiving portion so as to be movable together with the driving force receiving portion relative to the developing roller in the direction crossing the axis of the developing roller;
• and
• an abutting portion for receiving the supporting portion urged by the urging member,
• wherein the abutting portion is positioned outside an outer periphery of the photosensitive drum in a plane perpendicular to the axis of the developing roller, and
• wherein one of the developing roller and the coupling member is configured to rotate in a clockwise direction and the other of the developing roller and the coupling member is configured to rotate in a counterclockwise direction.
