PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor having high resolution, and high image quality and also having durability against the occurrence of the scraping and the damage of a surface caused by rubbing by providing a conductive supporting body with a coating obtained by anodizing aluminum and incorporating binder resin and conductive particles whose average sizes are equal to or under a specified value into a surface protective layer. SOLUTION: As for the electrophotographic photoreceptor 1 constituted by successively laminating a photoreceptive layer and the surface protective layer on the conductive supporting body, the conductive supporting body has the coating obtained by anodizing the aluminum and the surface protective layer incorporates the binder resin and the conductive particles whose average sizes are <=0.3μm. Thus, the photoreceptor 1 is constituted of an aluminum supporting body and the photoreceptive layer and the surface protective layer formed on a supporting body, and the photoreceptive layer is made thin as a means for sharpening an electrostatic latent image, and the sensitive body 1 has an anodized coating on the surface of the aluminum supporting body. Plural elements out of elements such as the photoreceptor 1, a primary electrifying means 3 and a cleaning means 9 or the like are integrally combined as a processing cartridge 11.
