Since the process cartridge is detachably mountable with respect to the apparatus main body, maintenance of the apparatus is facilitated. An electrophotographic image forming apparatus adopting an electrophotographic image forming method operates as follows: an electrophotographic photosensitive member uniformly charged by a charger is selectively exposed by light of an image forming apparatus to form an electrostatic latent image, the latent image is developed with toner by a developer to form a toner image, and the formed toner image is transferred onto a recording medium by a transfer device to form an image on the recording material.
Generally, a photosensitive assembly of the process cartridge is provided with a power receiving device, which is engaged with a machine driving device in the image forming apparatus to drive the photosensitive assembly to rotate so as to drive the entire process cartridge to operate. However, the photosensitive member needs to be detachably mounted in the image forming apparatus along with the process cartridge, and therefore, when the process cartridge is required to be removed from the image forming apparatus, the power receiving means is disengaged from the machine driving means to ensure that the process cartridge is smoothly removed from the image forming apparatus; when the processing box is installed in the image forming device for printing operation, the power receiving device is required to be meshed with the machine driving device, and the photosensitive assembly is ensured to smoothly receive driving force.
