Abstract
Disclosed is a laminated photosensitive plate for electrophotography, which comprises a conductive substrate, a charge generating layer containing a photoconductive organic pigment, which is formed on the surface of the substrate, and a charge transporting layer formed on the charge generating layer, wherein the charge transporting layer is formed of a homogeneous composition comprising an electron-donative polymeric photoconductor and a fused ring-containing, electron-donative polycyclic aromatic hydrocarbon incorporated in the polymeric photoconductor in an amount of 0.05 to 3 parts by weight per part by weight of the polymeric photoconductor. In this laminated photosensitive plate, by incorporation of the fused ring-containing, electron-donative polycyclic aromatic hydrocarbon into the charge transporting layer, not only mechanical properties such as abrasion resistance, toughness and adhesion but also electrophotographic characteristics such as initial saturation surface voltage, sensitivity and residual voltage can prominently be improved.
