Electrophotographic photoconductor

An electrophotographic photoconductor, comprising:

• a) an electroconductive substrate;
• b) a photoconductive layer formed thereon, comprising a charge generating material, and a vinylidene compound serving as a charge transporting material, which is selected from the group consisting of a vinylidene compound of the formula (I):
• ##STR153## wherein Ar represents an aromatic group selected from the group consisting of pyrenyl, phenanthrenyl and anthracenyl, and said group substituted by amino, cyano, nitro, alkyl of 1 to 8 carbon atoms, halogen and alkoxycarbonyl of the formula:
• --COOC.sub.n H.sub.2n+1
• wherein n is an integer of 1 to 8;
• and a vinylidene compound of the formula (II):
• Ar--CH.dbd.C(COOR).sub.2
• wherein Ar represents an aromatic group selected from the group consisting of pyrenyl, phenanthrenyl and anthracenyl, and said groups substituted by amino, cyano, nitro, alkyl of 1 to 8 carbon atoms, halogen and alkoxycarbonyl of the formula:
• --COOC.sub.n H.sub.2n+1
• wherein n is an integer of 1 to 8, and R is an alkyl group having 1 to 8 carbon atoms, which are unattached or which form a ring in combination together.
