ABSTRACT:
Photoconductors comprise a substrate, a charge transport layer and a charge generation layer, wherein the charge transport layer comprises binder and a first charge transport compound and the charge generation layer comprises binder, a charge generation compound and a second charge transport compound. The first and second charge transport compounds may be the same or different. In a first embodiment, the second charge transport compound is effective as a dopant in the charge generation layer and the weight ratio of the charge generation compound to the second charge transport compound in the charge generation layer is not less than about 1:3. In a second embodiment, the charge generation layer is formed on the substrate and the charge transport layer is formed on the charge generation layer. In a third embodiment, the charge generation layer comprises at least about 15 weight percent, based on the weight of the charge generation layer, of the charge generation compound.
