    Abstract: Exemplary embodiments provide charge generating layers and electrographic imaging members containing the charge generating layers. In various embodiments, an imaging member can be a multilayered photoconductive imaging member with a charge generating layer including, for example, a photogenerating pigment, such as a metal phthalocyanine; a dopant material, such as a multiple halide compound dopant and/or an ether dopant; and a binder or polymer. The imaging members can exhibit high photosensitivity, low residual potential (Verase), and excellent cyclic/environmental stability and can be used as photoreceptors, photosensitive members, and the like, in a machine of copy, printer, fax, scan, multifunction machines, and the like.

    Abstract: The present invention relates to photoconductive elements having an electrically conductive support, an electrical barrier layer and, disposed over the conductive layer, a charge generation layer capable of generating positive charge carriers when exposed to actinic radiation. The electrical barrier layer, which restrains injection of positive charge carriers from the conductive support, comprises a crosslinkable condensation polymer having as a repeating unit a planar, electron-deficient, tetracarbonylbisimide group and optionally a crosslinker.
