A photosensitive member having at least two electrically operative layers is dis~ closed. 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 an electrically inactive, organic, resinous material containing from about 15 to about 50 percent by weight of:

wherein X is selected from the group consisting of 0, 5, Se, Te and ~N~Rwhere R is an alkyl with from 1 to 10 carbon atoms and Y is selected from the group consisting of 5, Se, Te and C=C. The charge transport layer while substantially nonabsorbing

in most of the spectral region of intended use is uactive~in that it allows injection of photogenerated holes from the photoconductive layer, and allows these holes to be transported through the charge transport layer. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to

light and development.
