Abstract

An electrophotographic photoreceptor having formed on an electrically conductive support a light-sensitive layer containing a hydrazone derivative of formula (I) as a photoconductive material is disclosed: ##STR1## wherein Z is a divalent hydrocarbon group necessary to form in conjunction with a nitrogen atom a 5- or 6-membered nitrogen-containing heterocyclic ring condensed to the benzene ring; R.sub.1 is an aryl group or a heterocyclic group; R.sub.2 is a hydrogen atom, an alkyl group or an aryl group; X is a hydrogen atom, a halogen atom, an alkyl group, a substituted amino group, an alkoxy group or a cyano group; and n is an integer of 0 or 1. This hydrazone derivative exhibits great carrier transporting ability when it is incorporated in the light-sensitive layer.
