Abstract:
An electrophotographic imaging member comprisinga flexible supporting substrate,an undercoat layer,a charge generating layer comprisingbenzimidazole perylene photoconductive pigment particles andpoly(4,4'-diphenyl-1,1'-cyclohexane carbonate) film forming binder, anda charge transport layer formed from a coating solution, the coating solution comprisinga polycarbonate film forming binder andcharge transporting molecules, the charge transporting molecules comprisingbetween about 30 percent by weight and about 50 percent by weight alkyl derivative of an arylamine selected from the group consisting of N,N'-bis(alkylphenyl)-[1,1'-biphenyl]-4,4'-diamine wherein the alkyl is selected from the group consisting of methyl, ethyl, propyl and n-butyl, N,N'-diphenyl-N,N'-bis (chlorophenyl)-[1,1'-biphenyl]-4,4'-diamine, N,N'-diphenyl-N,N'-bis(3""-methylphenyl)-(1,1'-biphenyl)-4,4'-diamine anda second transport molecule comprising between about 5 percent by weight and about 25 percent by weight alkyloxy derivative of an arylamine selected from the group comprising N,N'-diphenyl-N, N'bis[3-methoxyphenyl]-1,1'-biphenyl]-4,4'diamine, N,N'-diphenyl-N,N'bis[4-methoxyphenyl]-1,1'-biphenyl]-4,4'diamine, 4-methoxyphenyldiphenylamine, bis[4-methoxyphenyl]phenylamine, tris[4-methoxyphenyl]amine, and mixtures thereof, the percent by weight being based on the total weight of solids in the coating solution,the charge generating layer being located between the substrate and the charge transport layer.
