The present invention, the organic photosensitive member is electrically conductive substrate relates to an organic photoreceptor employing an overcoat layer formed from this composition and the top coat for forming an organic photosensitive body; A photosensitive layer formed on the electrically conductive substrate thereon; The photosensitive layer formed thereon, characterized in that it comprises an overcoat layer of the overcoat layer-forming composition comprising an organic silane compound, an alcohol-soluble polymer, and a solvent of formula I as a product obtained by coating and heat treatment. The formula, R 'is C1-C20 alkyl group, a phenyl group, a vinyl group, a methacryloxypropyl group, an aminopropyl group, aminoethyl aminopropyl group, a phenylamino-propyl group, chloropropyl group, a mercaptopropyl group, an acryloxy propyl group, a 3-glycidoxypropyl group, a trifluoropropyl group, a heptadecyl big one selected from the group consisting of a group, and propyl isocyanate to fluoro, and, R '' is a hydrolyzable functional group, alkoxy group of C1-C20 or a halogen atom. According to the invention, an organosilane compound, an alcohol-soluble polymer and a case of forming the overcoat layer by the overcoat layer-forming composition comprising a solvent, it becomes essentially necessary primer or adhesive coating that were required for the adhesion improving film coating it is possible to simplify the process. And it is possible to improve the wear resistance is excellent in electrophotographic organic photoconductor for life. In addition, when the electrophotographic image of forming, to mitigate the decrease and increase of the residual potential of the charge potential can be manufactured according to the life property enhanced organophotoreceptor.
