Abstract
An imaging member having an adhesive charge transport layer is disclosed herein. The charge transport layer comprises a low surface energy polymer having siloxane segments in its backbone and a charge transport compound; it may further comprise a film-forming polymer. The charge transport layer has low surface energy, reduced coefficient of surface contact friction, and improved surface lubricity.
Claims16
An imaging member having an outermost exposed charge transport layer comprising:
- a charge transport compound;
- and
- a low surface energy polymer, wherein the low surface energy polymer has the structure of Formula (III):
- wherein x, y, and z are integers representing the number of repeating units;
- and x is at least 1.
An imaging member having an outermost exposed charge transport layer,
- wherein the charge transport layer comprises a film forming polymer, a charge transport compound, and a low surface energy polymer having siloxane segments in its backbone;
- wherein the charge transport layer has a bottom layer and a top layer;
- wherein the bottom layer comprises the film forming polymer and the charge transport compound, but does not include the low surface energy polymer;
- and
- wherein the top layer comprises the low surface energy polymer and the charge transport compound, but does not include the film forming polymer;
- wherein the low surface energy polymer has the structure of Formula (III):
- wherein x, y, and z are integers representing the number of repeating units;
- and x is at least 1.
An imaging member having an outermost exposed charge transport layer,
- wherein the charge transport layer comprises a film forming polymer, a charge transport compound, and a low surface energy polymer having siloxane segments in its backbone;
- wherein the charge transport layer has a first layer, one or more intermediate layers, and a last outermost layer;
- wherein the first charge transport layer contains no low surface energy polymer;
- wherein the weight percent of low surface energy polymer in each intermediate layer increases going in the direction from the first layer to the last layer, the weight percent in each intermediate layer based on the total weight of that intermediate layer;
- and
- wherein the last layer does not contain the film forming polymer.
