摘要
The invention described in the specification provides an improved coating for an electrophotographic photoconductor printing system. In particular, a blend of polycarbonate-A and polycarbonate-Z binders according to the formula: wherein R1 is selected from the group consisting of CH2 an alkylidene group, a cycloalkyl group and a substituted cycloalkyl group, R2 and R3 are selected from the group consisting of hydrogen, halogen and an a CH3 group provides increased durability and wear properties to a charge transport layer coated onto a charge generation layer of a photoreceptor drum. The polycarbonate blend may be used with amine and hydrazone charge transport materials and the charge transport layer may include additional additives which further improve the wear properties of the photoconductor coatings in a laser printer.
