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.
