PROBLEM TO BE SOLVED: To provide an electrophotographic image forming device capable of precisely maintaining the positional relation between a process cartridge and the image forming device at the completion time of loading in order to maintain an appropriate operational feeling and to obtain the excellent image. SOLUTION: This process cartridge is provided with an arm member 50 linked with an open/closing cove 20b of the image forming device, and a cam 51 capable of turning a projection 18 in the pressing direction as process cartridge positioning means, pressing a torsion coil spring 52 for position/fixing the process cartridge, in following up the movement of an arm member 50, through the torsion coil spring 52. Since the spring 52 is prevented from pressing a projection 18 at the time of loading/unloading the process cartridge, the operation feeling is improved and simultaneously the projection 18 is prevented from damaging. |
