Abstract
A photosensitive member having at least two electrically operative layers is disclosed. The first layer comprises a photoconductive layer which is capable of photogenerating holes and injecting photogenerated holes into a contiguous charge transport layer. The charge transport layer comprises a polycarbonate resin containing from about 25 to about 75 percent by weight of one or more of a compound having the general formula: ##STR1## wherein X is selected from the group consisting of an alkyl group having from 1 to about 4 carbon atoms (e.g. methyl, ethyl, propyl, butyl, etc.) and chlorine in the ortho, meta or para position. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.
