Abstract
An electrophotographic photoreceptor comprising a conductive substrate having formed thereon a photosensitive layer containing at least a charge generating material, a charge transporting material, and a binder resin, wherein said charge transporting material comprises a benzidine compound and/or a low-molecular weight charge transporting material having a molecular weight of from 200 to 400 and said binder resin mainly comprises a polycarbonate resin comprising a recurring unit represented by formula (I): ##STR1## and having a viscosity-average molecular weight ranging from 50,000 and 100,000, said charge transporting material and said binder resin being at a weight ratio of from 25:75 to 60:40. The photoreceptor exhibits improved abrasion resistance and improved peeling resistance while retaining excellent electrical and image characteristics.
