  • Imaging member
    Publication number: 20070141491
    Abstract: An imaging member comprising a barrier or under-layer intermediate a photogenerating layer and charge transport layer to reduce charge deficiency spots. The barrier under-layer comprises a film forming polymer binder selected from a conductive polymer binder, a non-conductive polymer binder, or mixtures thereof. Optionally, the barrier layer can include a small amount of a charge transport material.

  • Photoreceptor with three-layer photoconductive layer
    Publication number: 20060292466
    Abstract: An imaging member includes a conductive substrate, a charge generating layer, a charge transport layer, and an intermediate layer between the charge generating layer and the charge transport layer, the intermediate layer including a hole transport material, such as three different hole transfer materials, dispersed in a film forming binder, such as two different binder materials.

  • Imaging member
    Publication number: 20060286471
    Abstract: An imaging member includes a charge generating layer and a charge transport layer. The charge transport layer includes a first surface in contact with the charge generating layer and a second surface. The charge transport layer includes a film forming polymer binder and a charge transport component dispersed therein. The concentration of the charge transport component in the charge transport layer is at a peak in a region of the charge transport intermediate the first and second surfaces of the charge transport layer.

  • Imaging member
    Publication number: 20060068309
    Abstract: A charge transport layer for an imaging member comprising a charge transport material with a nitrogen molecular defense system not exhibiting early onset of charge transport layer fatigue cracking. The nitrogen molecular defense system includes attaching bulky organic groups to charge transport materials. The bulky groups aid in preventing recrystallization of the charge transport molecule and shield the nitrogen from molecular attack, such as by oxidation. The charge transport layer exhibits excellent wear resistance, excellent electrical performance, and outstanding print quality.

  • Photoconductive members
    Publication number: 20050014080
    Abstract: A photoconductive imaging member comprised of a photogenerating layer, and a charge transport layer containing a binder and a fluoropolymer generated by the free radical polymerization of a fluoroalkyl (methyl)acrylate and an alkyl(methyl)acrylate.
