Trigonal Se layer overcoated by
bis(4-diethylamino-2-methylphenyl)phenylmethane containing polycarbonate
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.
