Abstract: An imaging member comprising a layer of particulate photoconductive material dispersed in an organic resinous binder, said photoconductive material comprising trigonal selenium containing a mixture of an alkali metal selenite and an alkali metal carbonate. This layer can be the charge generation layer of an imaging member also having a charge transport layer in contact therewith.

Abstract: A photosensitive member having at least two operative materials. The first material comprises a photoconductive material which is capable of photogenerating and injecting photoexcited holes into a contiguous electronically active material. The electronically active material is catalytically synthesized from vinyl derivatives of suitable polycyclic compounds exemplified by phenyl substituted aromatic or heterocyclic groups such as a phenylnaphthalene, a phenylanthracene, a phenylindole, a phenylpyrene and corresponding polymers thereof, the active material being substantially non-absorbing in the wavelength of xerographic use and capable of transporting photogenerated holes. The photoconductive and electronically active materials may be combined in binder or layered xerographic plate configurations.

Abstract: Active polymeric matrices, xerographic elements and a process for obtaining the monomer and polyester material by reacting an aldehyde of a desired polycyclic aromatic compound with a dicarboxy acid ester in the presence of a base to obtain an unsaturated dicarboxyester intermediate; cyanating the intermediate in the presence of alcohol to obtain a saturated B-cyano monocarboxy acid ester which is hydrolyzed to the .alpha., .beta. dicarboxy intermediate and then esterified to obtain the .alpha., .beta. dicarboxy ester monomer. This monomer is catalytically polymerizable with a polyhydroxy alcohol such as a glycol to obtain the polyester.

Abstract: This application relates to a new way of carrying out xerographic functions while minimizing development and cleaning problems commonly associated with the photoreceptor surface and while maintaining excellent photoconductor efficiency and flex; and a device for carrying out the above purposes.
