摘要:
The present invention relates to a process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus. The process cartridge comprises an electrophotographic photosensitive drum; a developing roller for developing an electrostatic latent image formed on the electrophotographic photosensitive drum with the developer; a receiving side developer accommodating portion for accommodating the developer; a developer receiving opening for receiving the developer into the receiving side developer accommodating portion; a receiving side shutter portion movable between a developer reception permitting position for opening the developer receiving opening and a developer reception preventing position for closing the developer receiving opening; a regulating member; and a receiving side movable portion movable to interrelatedly move the receiving side shutter portion between the developer reception permitting position and the developer reception preventing position. The receiving side movable portion includes a first receiving side operating portion which takes an operating position when the receiving side shutter portion is at the developer reception preventing position and a second receiving side operating portion which takes an operating position when the receiving side shutter portion is at the developer reception permitting position.
