Electrophotographic member with hydrazone or ketazine compounds

Abstract

An electrophotographic photosensitive member is characterized by having a layer containing at least one of hydrazone group compounds represented by the following formula (1) or of ketazine group compounds represented by the following formula (2): ##STR1## In the formula, R.sub.11 and R.sub.12 independently of one another represent hydrogen, substituted or unsubstituted aryl, or substituted or unsubstituted heterocyclic radical; R.sub.13 and R.sub.14 independently of one another represent subsituted or unsubstituted alkyl, substituted or unsubstituted aralkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heterocyclic radical; and R.sub.15 represents a divalent organic residue. ##STR2## In the formula, R.sub.21, R.sub.22, R.sub.23, and R.sub.24 independently one another represent substituted or unsubstituted alkyl, substituted or substituted aralkyl, or substituted or unsubstituted aryl, or R.sub.21 and R.sub.22, together with the nitrogen which links them, represent cyclic amino radical, and R.sub.23 and R.sub.24, together with the nitrogen which links them, represent cyclic amino radical.
