Imaging member having a charge transport layer of a terphenyl diamine and a polycarbonate resin

An imaging member comprising a charge generation layer comprising a layer of photoconductive material and a contiguous charge transport layer of an electrically inactive polycarbonate resin material having dispersed therein from about 25 to about 75 percent by weight of one or more diamine compound having the general formula:

• ##STR3## wherein X.sub.1 and X.sub.2 are independently selected from the group consisting of a lower alkyl group having from 1 to about 4 carbon atoms, chlorine in the ortho, meta or para position, a para phenyl group and combinations thereof, said photoconductive layer exhibiting the capability of photogeneration of holes and injection of said holes and said charge transport layer being substantially nonabsorbing in the spectral region at which the photoconductive layer generates and injects photogenerated holes but being capable of supporting the injection of photogenerated holes from said photoconductive layer and transporting said holes through said charge transport layer.
