Disclosed is a photoconductor comprising a charge transport layer comprised of a mixture of a polyarylatecarbonate, a first charge transport compound, a second enylarylamine charge transport compound, and a fluoropolymer.
Photoconductors that include certain photogenerating layers and specific charge transport layers are known. While these photoconductors may be useful for xerographic imaging and printing systems, a number of them have a tendency to deteriorate, and thus have to be replaced at considerable costs and with extensive resources. A number of known photoconductors, inclusive of where there are present charging rolls, lack resistance to abrasion from dust, toner and/or carrier. For example, the surface layers of photoconductors are subject to scratches, which decrease their lifetime, and in xerographic imaging systems adversely affect the quality of the developed images. Although used photoconductor components may be partially recycled, there continues to be added costs and potential environmental hazards when recycling.
Thus, there is a need for photoconductors with extended lifetimes and reduced wearing characteristics.
There are provided the following Figures to further illustrate the photoconductors disclosed herein.
