<p>This invention is directed to an improved photoresponsive device comprised in the order stated of (1) a substrate, (2) a transmissive semi-conductive layer selected from the group consisting of indium-tin oxide, cadmium tin oxide, tin oxide, titanium oxides, titanium nitrides, titanium silicides, and mixtures thereof (3) a photogenerating layer comprised of an Inorganic photoconductive composition or an organic photoconductive composition, dispersed in a resinous binder and (4) a charge carrier transport layer comprised of a combination of a resinous binder having dispersed therein small molecules of an electrically active material, the combination of which is substantially non-absorbing to visible light and allows the injection of photogenerating holes from the charge photogeneratinglayer in contact therewith, the electrically active material being of the following formula: wherein X is selected from the group consisting of ortho CH3, meta CH3, para CH3, ortho C1, and para C1, as well as the incorporation of such devices in electrostatographic imaging systems.</p> |
