Abstract
A process kit includes a support member having a photosensitive member integrally mounted thereon together with process elements for acting on the photosensitive member. The support member is mountable on and removable from a main image forming apparatus having an optical system for projecting an image onto the photosensitive member. The support member has a positioning element for engaging the optical system in order to position the optical system accurately with respect to the photosensitive member. This configuration permits sharply formed images to be formed on the photosensitive member after removal and remounting of the process kit.
