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:

      , X , X and are selected from the group consisting of sulfur and selenium and ~, 3R,,, R~ and R

       14 are selected from the group consisting of hydrogen, alkyl from t to t~0carbon atoms, ~CO

2R wherein R is an alkyl from 1 to

10 carbon atoms

         0 The charge transport layer while substantially nonabsorbing in most of the spectral region of intended use is '~activ&'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.
