Charge generation layers comprise a charge generation compound and a binder which comprises polyvinylbutyral and phenolic resol. Dual layer photoconductors comprise the charge generation layer in combination with a substrate and a charge transport layer, in which the charge generation layer comprises a charge generation compound and a binder which comprises polyvinylbutyral and phenolic resol. Dual layer photoconductors comprise the charge generation layer in combination with a substrate and a charge transport layer, in which the charge generation layer comprises a charge generation compound and a binder which comprises polyvinylbutyral and a resin selected from the group consisting of phenol novolac and polyhydroxystyrene.

Charge generation layers comprising binder blends and photoconductors including the same

Charge generation layers comprising a binder and a charge generation compound, wherein the binder comprises a blend of methyl bisphenol A and an additional resin comprising an epoxy resin, a poly(phenylglycidyl ether)-co-dicyclopentadiene resin, a phenoxy resin or a polyhydroxystyrene resin. Dual layer photoconductors comprise the charge generation layer in combination with a substrate and a charge transport layer.

Solution squarylium charge generation systems incorporating binder blends

An electrophotographic photoconductor containing an aromatic polycarbonate binder resin and silicone microspheres provides improved wear resistance, increased useful life of the photoconductive drum, a high quality image over the life of the photoconductor, and improved coating uniformity.

Photoconductor containing silicone microspheres

A positive charging photoconductor of, preferably, 4 to 8 percent by weight metal-free phthalocyanine, 30-50 percent by weight tritolylamine and the remainder polyvinylbutyral.

Organic positive photoconductor
