摘要： A flexible imaging member comprising a slippery charge transport layer including a novel low surface energy polymer binder and a charge transport compound in the layer. In specific embodiments, the novel low surface energy polymer binder in the charge transport layer is a bisphenol A polycarbonate containing short polysiloxane segments present in the polycarbonate backbone—thus eliminating the light scattering effect to render optical clarity—and the charge transport compound is a diamine hole transporting species. The imaging member does include an anticurl back coating to maintain flatness.
