<p>A layered photoresponsive device comprising in the order stated a substrate (10); a transmissive semi-conductive layer (12) selected from the group consisting of indium-tin oxide, cadmium tin oxide, tin oxide, titanium oxides, titanium nitrides, titanium silicides, and mixtures thereof; a photogenerating layer (14) comprising an inorganic photoconductive composition or an organic photoconductive composition, dispersed in a resinous binder; and a charge carrier transport layer (16) comprising 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 photogenerating layer in contact therewith, the electrically active material being of the following formula:
<CHEM>
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> |
