Abstract
A laser printer is provided with a photoreceptor drum for transferring a toner image formed on a peripheral surface thereof to a sheet by rotating. The photoreceptor drum is stored in a process kit. In order to removably secure the process kit, a space is provided in an upper portion of a main body of the laser printer. A pair of bearings is provided in the process kit along a rotation shaft of the photoreceptor drum. Further, a pair of substantially U-shaped guides is provided for removably supporting the respective bearings in a direction substantially perpendicular to the rotation shaft. In this arrangement, since the installation and removal of the process kit can be done from the position above the main body, both the bearings and the guides can be exposed. This permits the respective positions of the bearings and the guides can be easily recognized, thereby ensuring an easy installation and removal of the process kit.
