摘要： A developing cartridge for developing a latent image formed on the photosensitive member, wherein the developing cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus, the developing cartridge includes a cartridge frame; a developing member for developing an electrostatic latent image formed on an electrophotographic photosensitive member; a toner accommodating portion for accommodating the toner to be used for use of the development by the electrostatic latent image; a driving force receiving member for receiving driving force for rotating the developing member from the main assembly of the electrophotographic image forming apparatus when the developing cartridge is mounted to the main assembly; a shutter movable between a cover position for covering a portion through which the developing member is exposed from the cartridge frame and a retracted position for permitting the developing means to be exposed; a flexible seal projected from a cartridge frame portion, which is extended in the longitudinal direction of the developing member and which is located opposed to a movement path of the shutter, at one and the other lateral sides, wherein the seal is effective to prevent the toner from the shuttering from the cartridge frame; wherein when the shutter is in the retracted position, one lateral side of the seal is contacted to an inner surface of the shutter.
