Abstract

An electrophotographic photoreceptor having a photosensitive layer which includes, as a resin binder, a copolymeric polyarylate resin having structural units of a Chemical Structural Formula 1, a method of producing the photoreceptor, an electrophotographic device including the electrophotographic photoreceptor, and a method of preparing the copolymeric polyarylate resin are provided. The electrophotographic photoreceptor reduces the amount of abrasion at the surface of a photoreceptor drum and lowers frictional resistance from the beginning until the end of printing, and moreover provides good images.
