Patent number: 7344809Abstract: An imaging member having a charge transport layer is provided. The charge transport layer includes a plurality of charge transport layers coated from solutions of similar or different compositions or concentrations, wherein the upper or additional transport layer(s) comprise a lower concentration of charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the first (bottom) charge transport layer may either be the same or different from that included in the additional charge transport layers. The charge transport compound in one or more of the layers is dissolved or molecularly dispersed in an electrically inactive polymer material to form a solid solution. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.Type: GrantFiled: November 16, 2006Date of Patent: March 18, 2008Assignee: Xerox CorporationInventors: Anthony M.
