    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.

    摘要： Hole transport polymers are disclosed. The polymers include modified triarylamine groups attached to a polymeric material such as, for example, poly(vinyl butyral). The polymers are particularly suited for use in multilayered photoreceptors. The polymers can be readily synthesized. Also disclosed are photoreceptors containing one or more layers that include the noted polymers.
