摘要: An imaging member is disclosed which includes a charge generating layer and a charge transport layer. The charge transport layer includes a first charge transport layer adjacent the charge generating layer and at least a second charge transport layer adjacent the first charge transport layer. Each charge transport layer includes a film forming polymer binder and a charge transport material dispersed therein. The first charge transport material has a composition which is the same or different than the second charge transport material and of a lower concentration. It may be selected from an aryl amine, aryl diamine, or combinations thereof. The combination has the effect of reducing charge deficient spots.

摘要: An imaging member having a charge transport layer with multiple regions or layers is provided. The charge transport layer includes at least two charge transport layers coated from solutions of different components and concentrations, wherein the second (top) transport layer comprises a lower concentration of different charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the second (top) charge transport layer is a high mobility hole transport compound. The charge transport compound in each layer is dissolved or molecularly dispersed in an electrically inactive film forming polymer to form a solid solution. In such a construction, the resulting dual charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.
