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 photogenerated holes into a contiguous charge transport layer. The charge transport layer comprises a polycarbonate resin containing from about 25 to about 75 percent by weight of one or more of a compound having a general formula: ##STR1## wherein R is selected from the group consisting of an alkyl group having from 1 to about 4 carbon atoms and chlorine in the ortho, meta or para position. This structure may be imaged in the conventional xerographic mode which usually includes charging, exposure to light and development.

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 photogenerated holes into a contiguous charge transport layer. The charge transport layer comprises an electrically inactive organic resinous material containing from about 10 to about 75 percent by weight of: ##STR1## R.sub.1 is selected from the group consisting of hydrogen (ortho) CH.sub.3, (meta) CH.sub.3, (para) CH.sub.3, and R.sub.2 is selected from the group consisting of hydrogen, (ortho) CH.sub.3, (meta) CH.sub.3, and (para) CH.sub.3. The charge transport layer while substantially non-absorbing in the spectral region of intended use is "active" 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.

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.

摘要： A photosensitive member having at least two electrically operative layers is disclosed. The first layer comprises trigonal selenium which is capable of photogenerating holes and injecting the photo-generated holes into a contiguous charge transport layer. The charge transport layer comprises a transparent electrically inactive organic resinous material containing from about 15 to about 75 percent by weight (throughout) 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 trigonal selenium carrier generating layer, and allows these photo-generated 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.
