Abstract: Disclosed is an organic photoreceptor which provides stable, high evenness of in-plane image density over a long period of time, and a production process of the organic photoreceptor. The organic photoreceptor includes a conductive support, an organic photosensitive layer, and a surface layer made of a cured resin, which are stacked in this order. The surface layer is obtained by curing a composition containing a radical polymerizable compound for forming the cured resin, metal oxide fine particles having a surface treated with a silane coupling agent, and a silane compound represented by the following general formula (1), wherein R1 to R3 each independently represent a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms, and at least one of R1 to R3 represents an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 20 carbon atoms.

Abstract: An electrophotographic image forming system forms an electrostatic latent image on at least a photoreceptor, develops an image using an electrostatic charge image developing toner, and removes the toner using a cleaning blade. A tip ridge of the cleaning blade is pressed against a surface of the photoreceptor. The system includes a photosensitive layer of the photoreceptor and a surface protecting layer that is provided on a surface of the photosensitive layer. The surface protecting layer includes a polymerizable monomer having at least two polymerizable groups in a molecule and a polymer of a hole transporting compound having a polymerizable group represented by General formula (1). The tip ridge of the cleaning blade has an edge angle that is obtuse and less than 120° and is pressed against the surface of the photoreceptor at an effective contact angle that is in a range of 8 to 20°.
