Estimating the term…
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.
An imaging member comprising:
A charge transport component composition comprised of a first charge transport layer and a second charge transport layer deposited thereon and in contact therewith, wherein the first charge transport layer is situated between a charge generating layer and the second charge transport layer, wherein each of said charge transport layers comprises charge transport components molecularly dispersed in a binder to form a solid solution, and wherein the weight percent of charge transport components in the second charge transport layer is less than the weight percent of the charge transport components in the first charge transport layer.
