Electrophotographic photoreceptor with polycarbonate resin mixture

摘要

An electrophotographic photoreceptor comprising a conductive substrate having formed thereon a photosensitive layer containing, as binder resins, (A) a polycarbonate resin comprising a recurring unit represented by formula (I): <IMAGE> (I) and (B) a polycarbonate resin comprising a recurring unit represented by formula (II) or (III): <IMAGE> (II) <IMAGE> (III) wherein X1 and X2 each represent a hydrogen atom or an alkyl group, or (B') a copolycarbonate resin comprising a recurring unit represented by formula (II) and a recurring unit represented by formula (IV): <IMAGE> (IV) said polycarbonate resin (B) or copolycarbonate resin (B') having a lower molecular weight than that of said polycarbonate resin (A). The photoreceptor had high film strength against abrasion and causes no toner filming or adhesion of any other foreign substances and is therefore excellent in electric characteristics and image characteristics.
