  • Flexible imaging members without anticurl layer
    Patent number: 8124305
    Abstract: The presently disclosed embodiments relate in general to electrophotographic imaging members, such as layered photoreceptor structures, and processes for making and using the same. More particularly, the embodiments pertain to the incorporation of a liquid compound having a high boiling point into the charge transport layer such that an anticurl back coating is no longer needed for reduction or elimination of photoreceptor layer curling.
    Type: Grant

  • Multilayered electrophotographic imaging member
    Patent number: 5686215
    Abstract: An electrophotographic imaging member including an electrophotographic imaging member having an imaging surface adapted to accept a negative electrical charge, the electrophotographic imaging member including a substrate, a siloxane hole blocking layer, an adhesive layer including a uniform blend of polyarylate film forming resin and a polyester film forming resin, a charge generation layer including hydroxygallium phthalocyanine particles dispersed in a film forming resin, and a hole transport layer, the hole transport layer being substantially non-absorbing in the spectral region at which the charge generation layer generates and injects photogenerated holes but being capable of supporting the injection of photogenerated holes from the charge generation layer and transporting the holes through the charge transport layer.
