ABSTRACT:
A process for preparing an electrophotographic imaging member comprising a substrate having an electrically conductive surface, a charge generating layer and a charge transport layer contiguous to the charge generating layer, the process comprising preparing a dispersion of finely divided photoconductive particles in a liquid in which the particles are insoluble, the liquid comprising at least 0.25 percent by weight of an alcohol based on the total weight of the liquid, applying a thin coating of the dispersion on a substrate, evaporating substantially all of the liquid from the coating, and embedding the particles in a film forming polymer matrix to form the charge generating layer.
