Abstract
A process cartridge removably mountable within an image forming apparatus, includes a frame, an image bearing body provided in the frame, a process device also provided in the frame and acting on the image bearing body, and an engagement portion. The engagement portion of the process cartridge is adapted to be engaged with a mounting portion of the image forming apparatus when the process cartridge is positioned at a predetermined mounting position, by utilizing a driving force from a drive source within the image forming apparatus. An image forming apparatus includes the mounting portion for mounting the removable process cartridge, a drive source for driving the process cartridge into mounted and dismounted positions, a mounting member for directing the process cartridge toward the mounting portion and a damper for dampening a shock received by the process cartridge. The image forming apparatus further includes a resilient pressing device for pressing against the mounted process cartridge so as to maintain the cartridge in a predetermined processing position. Mounting and dismounting of the process cartridge with respect to the image forming system can be effected automatically.
