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 R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are selected from the group consisting of hydrogen, an ortho, meta or para alkyl group having from 1 to about 4 carbon atoms, an ortho, meta or para halogen atom, a para phenyl group and combinations thereof.
