摘要:
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 the photo-generated holes into a contiguous charge transport layer. The charge transport layer comprises poly(N-vinylcarbazole) which contains an electrically active plasticizer comprising from about 1 to about 25 percent by weight of bis(4-diethylamino-2-methylphenyl)phenylmethane. The charge transport layer while substantially non-absorbing in the spectral region of intended use, is "active" in that it allows injection of photo-generated 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.
