  • Patent number: 7838187
    Abstract: 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.

  • Patent number: 7298983
    Abstract: 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.
