Abstract

An apparatus applicable to an image forming apparatus allows an image carrier and a cartridge accommodating image forming process units therein to be readily positioned relative to each other and allows the cartridge to be replaced with ease. The equipment has a cover on which a positioning member is provided. When the cover is closed, the positioning member positions the image carrier and cartridge which are received in the equipment relative to each other to in turn set up a predetermined relative position of the image carrier and process units. In the event of replacement of the cartridge and image carrier, a guide member is used to guide the cartridge relative to the equipment.
