Abstract
An electrophotographic element comprising a conductive substrate and a mono-layer type or multi-layer type photosensitive layer, superposed thereon, containing a photoconductive material in which said photoconductive material is a hydrazone compound having the following general formula (I) or an anile compound having the following general formula (II): ##STR1## [where R.sub.1 is a methyl, ethyl 2-hydroxyethyl or 2-chloroethyl group; R.sub.2 is a methyl, ethyl, benzyl or phenyl group; and R.sub.3 is chlorine, bromine, a C.sub.1 -C.sub.4 alkyl group, a C.sub.1 -C.sub.4 alkoxy group, a dialkylamino group with C.sub.1 -C.sub.4 alkyl or a nitro group.] ##STR2## [where R.sub.1 is the same as the said general formula (I); and R.sub.4 is a substituted or non-substituted phenyl, naphthyl, heterocyclic or C.sub.1 -C.sub.10 alkyl group.]
