Abstract:
1. An electrophotographic apparatus, including: 1) an electrophotographic photoreceptor having a support and a photosensitive layer placed on the support; 2) charging means for charging a surface of the electrophotographic photoreceptor; 3) exposing means for irradiating the surface of the electrophotographic photoreceptor charged by the charging means with exposure light to form an electrostatic latent image on the surface of the electrophotographic photoreceptor; 4) contact development means, that has a developer and a developer carrier for carrying a developer layer composed of at least the developer, for forming a developed image on the surface of the electrophotographic photoreceptor by bringing the developer layer carried on the developer carrier into contact with the surface of the electrophotographic photoreceptor to develop the electrostatic latent image; and 5) transferring means for transferring the developed image on the surface of the electrophotographic photoreceptor formed by the contact development means onto a transfer material, wherein a surface layer of the electrophotographic photoreceptor contains a diorganopolysiloxane wherein 0.01 to 20% of the mass of the surface layer is composed of said diorganopolysiloxane, wherein said diorganopolysiloxane has a repeating structural unit α represented by the following formula (11) and a repeating structural unit β represented by the following formula (12), and wherein the surface layer does not contain fluorine-atom containing resin particles: wherein in the formulae (11) and (12): R B D
