ABSTRACT:
A process cartridge is detachably mountable to a main assembly of the image forming apparatus. The cartridge includes an image bearing member, a developing device developing an electrostatic image formed on the member with a developer, a first receiver receiving a driving force rotating the member from a first transmitter of the main assembly, a second receiver receiving a driving force driving the developing device from a second transmitter of the main assembly. The first receiver and the transmitter are engaged with each other with play in a mounting and demounting direction of the process cartridge, when the driving force is inputted from the first transmitter to the first receiver. When the driving force is inputted from the second transmitter to the second receiver, a part of the process cartridge is urged toward a positioning portion for positioning of the process cartridge relative to the main assembly.
