Abstract
An organic photoreceptor having a photosensitive layer, an electric conductive support, and a protective layer is disclosed, in which the protective layer comprises a composition produced by reacting tin oxide particles an acryloyl or methacryloyl group on their surface with a compound having an acryloyl or methacryloyl group. A production method of the same, an image forming apparatus and a process cartridge using the same are also disclosed.
