ABSTRACT A process is provided for preparing an electrophotographic imaging member wherein the content of halogenated solvents in the charge transport layers is reduced, the member having stable electrical properties during extended use. According to the process a coating is deposited on a photoconductive layer, the coating comprising a solution of a polycarbonate resin material having a molecular weight of from about 20,000 to about 120,000, from about 25 to about 75 percent by weight of a diamine compound based on the total weight of the polycarbonate resin, the diamine compound of one or more compounds having the general formula Image wherein X is selected from the group consisting of an alkyl group, having from 1 to about 4 carbon atoms and chlorine, a halogenated hydrocarbon solvent and a halogen free organic solvent having a boiling point greater than the boiling point of the halogenated hydrocarbon solvent, the weight ratio of the halogen free organic solvent to the halogenated hydrocarbon solvent being between about 1 to 99 and about 50 to 50. The coating is heated to remove at least substantially all of the halogenated hydrocarbon solvent.
