  • Photoconductive imaging member
    Patent number: 7704656
    Abstract: A photoreceptor comprising a charge transport layer doped with a polyarylate polymer is provided. A charge transport layer is doped with about 0.1 to about 10.0% by weight, solids basis, of a polyarylate polymer, such as for example Ardel. Charge transport layers doped with a polyarylate polymer exhibit improved electrical performance in terms of lower Vr and VBG values.
    Type: Grant

  • Electrophotographic imaging members
    Patent number: 6645686
    Abstract: An electrophotographic imaging member comprises a substrate, a charge generating layer, and a charge transport layer. The charge transport layer comprises a binder and charge transport molecules, wherein the binder eliminates or minimizes crystallization of the charge transport molecules. Optionally, an electrophotographic imaging member comprises a substrate and a single charge generating and charge transport layer. The single charge generating and charge transport layer comprises a binder, charge generating molecules and charge transport molecules, wherein the binder eliminates or minimizes crystallization of the charge transport molecules. Specific binders are PCZ-800, a PCZ-500, or a PCZ-400 polycarbonate resin.

  • Anticurl backing layer in electrostatographic imaging members
    Patent number: 6132923
    Abstract: A flexible electrostatographic imaging member having at least a first parallel side and a second parallel side, the imaging member includinga supporting substrate layer,at least one imaging layer on one side of the substrate layer,and an anticurl backing layer on the opposite side of the substrate layer, the anticurl backing layer includinga major central region having a substantially uniform thickness,a first minor edge region along the first parallel side, anda second minor edge region along the second parallel side, the first minor edge region and the second edge region each having a thickness greater than the thickness of the major central region.A process for fabricating the imaging member is also disclosed.
