Patent ID: 7544451

Claim:
An electrophotographic imaging member comprising a) a substrate; and thereover b) a charge transport layer formed from a formulation comprising N,N′-diphenyl-N, N-bis(3-methylphenyl)-1,1′-biphenyl-4,4′-diamine, a poly(4,4′-dihydroxy-diphenyl-1-1-cyclohexane) polycarbonate binder, a polytetrafluoroethylene and an antioxidant lubricant additive, the antioxidant lubricant additive being selected from the group consisting of benzene propanoic acid 3,5-bis(1,1-dimethylethyl)-4-hydroxy-C 13 -C 15 branched and linear esters, 2,2′-thiodimethylene bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate, 4,4′-thio bis (2,6-di-tert-butyl phenol), 4,4′-methylene bis (2,6-di-tert-butyl phenol), and mixtures thereof, wherein the imaging member exhibits increased wear resistance by from about 20 percent to about 30 percent as compared to the imaging member without the antioxidant lubricant additive.
