PROBLEM TO BE SOLVED: To make it possible to obtain stable potential characteristics and good images under the entire environment from a low temp. and low humidity to high temp. and high humidity even if the photosensitive layer of an electrophotographic photoreceptor is made thin by specifying the film thickness of a photosensitive layer to a specific value or below and forming an aluminum base having an anodically oxidized film. SOLUTION: The film thickness of the photosensitive layer of the electrophotographic photoreceptor 1 is specified to <12μm. As a result, the high-quality images which are more sharpened in the potential distribution of the electrostatic latent image on the surface of the electrophotographic photoreceptor 1 and faithfully reproduced in the dots of digital light are obtd. The anodically oxidized film is formed on the surface of the aluminum base. As a result, the charge implantation from the substrate is prohibited even under a high electric field by the thin film and the high-grade and high-stability images having the excellent environment stability and durable stability are obtd. The process cartridge integrally supports the means selected from a group consisting of the electrophotographic photoreceptor 1, an electrostatic charging means 3, a developing means 3 and a cleaning means 9 and is freely attachable and detachable to and from the electrophotographic device body.
