ABSTRACT:
An imaging member comprising a hole generation layer and a contiguous hole transport layer, said generation layer comprising a photoconductive material exhibiting the capability of photogeneration of holes and injection of said holes, said hole transport layer comprising a di or triarylmethane compound of the general formula: ##STR1## wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of a C.sub.1 -C.sub.8 alkyl, aryl, alkaryl and aralkyl, where said aryl is a phenyl group or a condensed ring group, where the alkyl group of said alkaryl and aralkyl is a C.sub.1 -C.sub.4 group; R.sub.3 is independently selected from the group consisting of hydrogen and CH.sub.3 ; and R.sub.4 is the same as R.sub.1 and R.sub.2 or a disubstituted aminophenyl group wherein the substituents are independently selected from the group consisting of a C.sub.1 -C.sub.8 alkyl, aryl, alkaryl and aralkyl as defined supra, said di or triarylmethane is dissolved in a polycarbonate resinous material, said charge transport layer being substantially nonabsorbing in the spectral region at which the photoconductive material generates and injects said holes, but being capable of supporting the injection of said holes and transporting said holes through said transport layer and dissolved in said transport layer a stabilizing proportion of a substituted or unsubstituted 2-(2'-hydroxyphenyl)-benzotriazole.
