An electrophotographic photoreceptor is disclosed, which comprises an electrically conductive support having provided thereon a photoconductive layer containing, as a charge transport material, a compound represented by formula (I) ##STR1## wherein R.sub.1 represents an alkyl group, and R.sub.2 and R.sub.3, which may be the same or different, each represents a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom, an alkoxycarbonyl group, or a substituted amino group. The photoreceptor satisfies both electrical and mechanical requirements without undergoing adverse influences from binder resins used therein.
