Abstract:
1. A process cartridge detachably mountable to a main assembly of the image forming apparatus, said process cartridge comprising: an image bearing member; a developing device configured and positioned to develop an electrostatic image formed on said image bearing member with a developer; an image bearing member driving force input portion configured and positioned to receive a driving force for rotating said image bearing member from an image bearing member driving force output portion from the main assembly of the image forming apparatus; a developing device driving force input portion for receiving a driving force for driving said developing device from a developing device driving force output portion of the main assembly of the image forming apparatus, wherein the image bearing member driving force output portion and said image bearing member driving force input portion are engaged with each other with play in a mounting and demounting direction of said process cartridge, when the driving force for rotating said image bearing member is inputted from said image bearing member driving force output portion to said image bearing member driving force input portion, and wherein when the driving force for rotating said developing device is inputted from said developing device driving force output portion to said developing device driving force input portion, a part of said process cartridge is urged toward a positioning portion that positions said process cartridge relative to the main assembly.
