Abstract
An image forming device, a process cartridge engageable with the same and a method for firmly positioning the process cartridge in the image forming device. The image forming device includes a main frame and a main frame driving gear, wherein a guide rail is respectively arranged on left and right sides of the inside of the main frame. An installation section is arranged at a tail end of each guide rail and the installation section and guide rail respectively define a reverse hook-shape. Lugs formed at both ends of a housing of the process cartridge are driven by a radial component of driving force of the image forming device to the process cartridge to closely bear against walls of installation sections at the tail ends of the guide rails when the process cartridge is in an operating state in the image forming device.
