Abstract
Conventionally, an electrophotographic image forming apparatus by means of an electrophotographic image forming process has a process cartridge which integrates the electrophotographic photosensitive body and process means into a cartridge which can be detachably mounted on the image forming apparatus. In order to obtain a fine image in that kind of image forming apparatus, it is necessary that the process cartridge is mounted accurately at a predetermined position in the image forming apparatus and interface portions of various electrical contacts and driving transmission part are accurately connected. For improvement, process cartridges having well mountability are provided.
