Abstract
A photoconductor for use in electrophotographic reproduction devices is disclosed. This photoconductor exhibits improved oil resistance when used with liquid toners and excellent cycling stability. The photoconductors of the present invention utilize a phthalocyanine dye, particularly an X-form metal-free phthalocyanine, dispersed in a medium molecular weight polyvinyl chloride binder in the charge generating layer, and a charge transport molecule, particularly a hydrazone such as DEH, in a polyestercarbonate binder in the charge transport layer.
