Abstract
A photoconductor having a charge generation layer of pigment and a binder resin of a thorough mixture of polyvinylbutyral, a polysiloxane, and, preferably, a phenolic resin. An optimum formulation was Type IV oxotitanium phthalocyanine in a binder of, by weight 50 parts polyvinylbutyral, 45 parts poly(methyl-phenyl)siloxane, and 5 parts polyhydroxystyrene. This photoconductor provides excellent electrical properties and consistent, economical coating results.
