Abstract
An electrophotographic element is prepared by forming a photoconductive layer containing a hydrazone compound therein on an electroconductive support member. The hydrazone compounds represented by the following general formula, are useful as photoconductive materials and as charge transport materials for use in electrophotography: ##STR1## wherein Ar represents a substituted or unsubstituted condensed polycyclic group or heterocyclic group, and R represents a methyl group, an ethyl group, a benzyl group or a phenyl group. The condensed polycyclic group includes a naphthalene ring, and an anthracene ring. The heterocyclic ring includes nitrogen, oxygen and sulfur.
