ABSTRACT OF THE DISCLOSURE This invention relates to an electrophotographic imaging member or device and an imaging method using this imaging member, which member or device is comprised of a sub- strate, a layer of a charge carrier injecting material com- prised of carbon or graphite dispersed in a polymer, a layer of a charge carrier transport material, a layer of a photo- conductive charge carrier generating material and an electri- cally insulating overcoating layer. In one embodiment the imaging member is layered and comprises from the bottom up a substrate; a layer of material comprised of carbon black dis- persed in a polymer, and capable of injecting holes into a layer on its surface; a hole transport layer in operative con tact with the layer of hole injecting material which transport layer comprises a combination of an electrically inactive organic resin having dispersed therein an electrically active material, the combination of which is substantially nonabsorbing to visible electromagnetic radiation, but allows the injecting of photogenerated holes from a charge generator layer in con- tact with the hole transport layer and electrically induced holes from the layer of injecting material; a layer of charge generating material on and in operative connection with the charge transport layer and a layer of insulating organic resin overlaying the layer of charge generating material.
