Abstract: Embodiments provide novel imaging members used in electrostatography. More particularly, there is provided flexible electrophotographic imaging members which have improved imaging layer(s) formulated to comprise of a plasticizer in a material matrix of a solid solution comprising a charge transporting compound and a film forming polymer binder which is a novel A-B diblock copolymer or a binary polymer blend of a novel A-B diblock copolymer and a bisphenol polycarbonate. The flexible imaging members thus prepared have improved photoelectrical cyclic function stability, chemical resistive property, and are curl-free, and thus eliminate the need for an additional anticurl back coating layer.

Abstract: 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.

Abstract: A method involving a photoreceptor having a front surface and a rear surface, including: (a) creating an electrostatic latent image on an image area of the photoreceptor front surface; (b) developing the latent image with developer particles to form a developed image; (c) transferring the developed image off the photoreceptor wherein the photoreceptor retains residual charges in the image area after the transferring of the developed image off the photoreceptor; and (d) discharging at least a portion of the residual charges in the image area, after transferring the developed image off the photoreceptor, by directing charge dissipation emissions at a portion of the image area and at a corresponding region on the photoreceptor rear surface directly opposite the image area portion.
