摘要:
An improved layered photoresponsive device comprised of a substrate, a photogenerating layer, comprised of inorganic photoconductive composition, or an organic photoconductive composition, a charge carrier transport layer in contact with the photogenerating layer, which transport layer is comprised of electrically active molecules of the formula: ##STR1## dispersed in a highly insulating and transparent organic resinous material, wherein X is selected from the group consisting of (ortho) CH.sub.3, (meta) CH.sub.3, (para) CH.sub.3, (ortho) Cl, (meta) Cl, (para) Cl; and as a top coating in contact with the charge carrier transport layer, an arylmethane of the formula: ##STR2## wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of alkyl groups, aryl groups, alkylaryl groups and arylalkyl groups, R.sub.3 is independently selected from the group consisting of hydrogen, and methyl, R.sub.4 is independently selected from the group consisting of alkyl groups, alkylaryl groups, arylalkyl groups, and a disubstituted aminophenyl group, wherein the substituents are independently selected from the group consisting of alkyl, aryl, alkylaryl, and arylalkyl, as well as the use of such devices in electrostatic latent imaging systems.
