Patent attributes
Provided is a process cartridge where a developing unit includes a coupling member that receives driving force, a driving transmission member that transmits the driving force from the coupling member to a driving roller, and a support member that rotatably supports the coupling member and is movable with respect to a developing frame in a direction intersecting with a rotational axis of the developing roller. The developing frame and the driving transmission member are configured to be movable with respect to a drum frame of a drum unit in the direction intersecting the rotational axis. In this process cartridge, an urging member that engages with both the support member and the drum frame is included such that an urging force is applied in a direction in which a positioned portion of the support member and a positioning portion of the drum frame contact each other.
