Abstract
An electrophotographic photoreceptor excellent in electric characteristics and having few defects in image quality, and an image forming method for forming an image free from defects in image quality by the contact charging system. The inventive electrophotographic photoreceptor comprising a conductive substrate having thereon an undercoat layer and a photosensitive layer, in which the undercoat layer comprises a copolymer resin having a hydrolytic silyl group. The copolymer resin having hydrolytic silyl groups is preferably an acrylic copolymer resin. Further, the undercoat layer may contain electrically conductive particles. When an image is formed using this electrophotographic photoreceptor, a method comprising contacting a charging device with a surface of the electrophoto-graphic photoreceptor and supplying charge from the outside to charge the photoreceptor can be employed.
