    摘要: A photoreceptor fabrication method including: (a) depositing a charge generating layer; (b) depositing a first charge transport layer having a first charge carrier mobility value; and (c) depositing a second charge transport layer having a second charge carrier mobility value that is different from the first charge carrier mobility value; wherein steps (a), (b), and (c) occur in any order, wherein the difference in the first charge carrier mobility value and the second charge carrier mobility value is accomplished by:(i) wherein the first charge transport layer includes a first binder and a first charge transport material and the second charge transport layer includes a second binder and a second charge transport material, selecting the first binder to have a lesser solubility limit for the first charge transport material than the solubility limit of the second binder for the second charge transport material; or(ii) wherein the first transport layer includes a first polymeric compound composed of a first charge transport moiety covalently bonded to a first binder moiety and the second transport layer includes a second polymeric compound composed of a second charge transport moiety covalently bonded to a second binder moiety, selecting the proportion of the first charge transport moiety in the first polymeric compound to be less than the proportion of the second charge transport moiety in the second polymeric compound.
