Abstract
A photosensitive member having at least two electrically operative layers. The first layer comprises a photoconductive layer which is capable of photogenerating and injecting photo-excited holes into a contiguous active layer. The active layer comprises a transparent organic material which is substantially non-absorbing in the spectral region of intended use, but which is 'active' in that it allows injection of photo-excited holes from the photoconductive layer, and allows these holes to be transported through the active layer. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light, and development.
