Patent number: 7862967Abstract: A photoconductor that includes a supporting substrate, a first photogenerating layer, a second photogenerating layer and at least one charge transport layer. The first photogenerating layer contains, for example, a phthalocyanine pigment, and the second photogenerating layer contains a different phthalocyanine pigment than the first photogenerating layer phthalocyanine.Type: GrantFiled: May 15, 2007Date of Patent: January 4, 2011Assignee: Xerox CorporationInventors: Jin Wu, Markus R.

Patent number: 7838187Abstract: The presently disclosed embodiments are directed to charge transport layers useful in electrostatography. More particularly, the embodiments pertain to an improved electrostatographic imaging member having a charge transport layer that is dual-dopant, wherein operating life improvement is achieved by incorporating a small amount of compatible thermalsetting resin and polyhedral oligomeric silsesquioxane into the layer. Incorporation of these resins have been shown to increase charge transport life.Type: GrantFiled: August 21, 2007Date of Patent: November 23, 2010Assignee: Xerox CorporationInventors: Liang-Bih Lin, Daniel V. Levy, Jin Wu, Robert W. Hedrick, Gary A. Batt, M. John Hinckel

Patent number: 7298983Abstract: The amount of lateral charge migration (LCM) on a photoreceptor is quantified by measuring the average potential of a latent image formed on the photoreceptor surface. The surface is first uniformly charged, then exposed a first time to an image. After a waiting period during which LCM may occur, the surface is exposed a second time to the image. After another waiting period, the average potential is measured. The amount of LCM may be quantified by varying the waiting periods.Type: GrantFiled: December 7, 2004Date of Patent: November 20, 2007Assignee: Xerox CorporationInventors: Markus Rudolf Silvestri, Surendar Jeyadev, Satchidanand Mishra, M.
