Abstract

A charge transport layer for an imaging member comprising a charge transport layer wherein the charge transport layer is coated in two passes and wherein the second pass comprises the application of a charge transport component and a hindered phenol covalently bonded to a polymer. The charge transport layer exhibits excellent wear resistance, excellent electrical performance, and excellent print quality.

Claims2

Dependent claims

An imaging member comprising:

a substrate;
