摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic image forming apparatus where a drawer member in which a photoreceptor drum and a developing unit are mounted is mounted in an apparatus body, which enables the photoreceptor drum and a developing roller to come into contact with each other and be separated from each other, and which achieves downsizing.;SOLUTION: An electrophotographic image forming apparatus comprises: a process cartridge; an apparatus body; and a drawer member 13 which detachably supports the process cartridge, and is movable between an inside position located inside the apparatus body and an outside position located outside the apparatus body. A contact/separation member 42, which can take a contact position for bringing a developing roller and a photoreceptor drum into contact with each other and a separation position for separating the developing roller and the photoreceptor drum from each other, is provided in the drawer member 13.;COPYRIGHT: (C)2015,JPO&INPIT
