Abstract
The present invention provides a novel hydrazone compound expressed by the general formula I ##STR1## (wherein Ar represents substituted or non-substituted naphthyl group, anthryl group, styryl group, pyridyl group, thienyl group, furyl group or carbazolyl group.); the process for manufacturing thereof; and a multilayer type electrophotographic element comprising an electrically conductive substrate and a charge carrier generating layer and a charge transfer layer as successively superposed on said substrate, said charge transfer layer containing a hydrazone compound, as effective ingredient, expressed by the general formula II ##STR2## (wherien Ar' represents condensed polycyclic rings such as substituted or non-substituted naphthalene ring, anthracene ring and the like; heterocyclic rings such as substituted or non-substituted furan ring, thiophene ring, pyridine ring, carbazole ring and the like; or substituted or non-substituted styryl group.)
