Abstract
An electrophotographic photoconductor is composed of an electroconductive substrate, and a photoconductive layer formed thereon, which contains a charge generating material, and a vinylidene compound of formula (I): ##STR1## wherein Ar represents an aromatic group; and X represents cyano group, an alkyl group having 1 to 8 carbon atoms, or an alkoxycarbonyl group represented by --COOC.sub.n H.sub.2n+1, in which n is an integer of 1 to 8; or a vinylidene compound of formula (II): EQU Ar--CH.dbd.C(COOR).sub.2 (II) wherein Ar represents an aromatic group; and R represents an alkyl group having 1 to 8 carbon atoms, which may form a ring in combination of two of the alkyl groups, each of these vinylidene compounds serving as a charge transporting material.
