ABSTRACT:
An electrophotographic photoreceptor includes a conductive substrate and a photosensitive layer on the conductive substrate. The photosensitive layer contains an arylamine compound of a formula (I): ##STR1## where A.sub.1, A.sub.2, A.sub.3 and A.sub.4 each independently represents a substituted or unsubstituted group selected from an alkyl group, an aralkyl group, an aryl group, a heterocyclic group and a condensed polycyclic group; Y represents a substituted or unsubstituted group selected from an alkylene group, an aralkylene group, an alkenylene group, an arylene group, and a bivalent heterocyclic group; and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 each independently represents a hydrogen atom or a substituent selected from a hydroxyl group, a halogen atom, and a substituted or unsubstituted group selected from an alkyl group, an alkoxy group, an aralkyl group, an aralkyloxy group, an aryl group, an aryloxy group, a heterocyclic group, a heterocyclicoxy group, a condensed polycyclic group and an amino group.
