Abstract (en)
[origin: EP0767411A1] A photoconductor for use in electrophotographic reproduction devices is disclosed. This photoconductor exhibits excellent cycling stability and minimized charge transport molecule leaching when used with liquid toners. Further, the photoconductor has a relatively high glass transition temperature. The photoconductors of the present invention utilize, as the binder in the charge transport layer, a specifically defined bisphenol A/bisphenol TMC polycarbonate copolymer which has a bisphenol A: bisphenol TMC weight ratio of from about 30:70 to about 70:30, preferably from about 35:65 to about 65:35, and a polymer molecular weight of from about 10,000 to about 100,000, preferably from about 20,000 to about 50,000.
