Abstract

A process for preparing an electrophotographic imaging member comprising providing a photogenerating layer on a supporting substrate and applying a charge transport layer forming mixture to the photogenerating layer, the charge transport layer forming mixture comprising a charge transporting aromatic amine compound of one or more compounds having the general formula: ##STR1## wherein R.sup.1 and R.sup.2 are an aromatic group selected from the group consisting of a substituted or unsubstituted phenyl group, naphthyl group, and polyphenyl group and R.sup.3 is selected from the group consisting of a substituted or unsubstituted aryl, and alkyl group having from 1 to 18 carbon atoms and cycloaliphatic group having from 3 to 12 carbon atoms, a polymeric film forming resin in which the aromatic amine is soluble, solvent for the polymeric film forming resin, and from about 1 part per million to about 10,000 parts per million, based on the weight of the aromatic amine, of a protonic acid or Lewis acid having a boiling point greater than about 40.degree. C. and soluble in the solvent.
