Patent ID: 7651827

Claim:
An imaging member comprising a) a substrate; and thereover b) a charge transport layer comprising a phosphorus-containing lubricant and charge transport molecules; wherein said charge transport molecules is selected from the group consisting of 1-phenyl-3-(4′-diethylamino styryl)-5-(4″-diethylamino phenyl)pyrazoline, N,N′-diphenyl-N,N′-bis(3-methylphenyl)-(1,1′-biphenyl)-4,4′-diamine, N-phenyl-N-methyl-3-(9-ethyl)carbazyl hydrazone, and 4-diethyl amino benzaldehyde-1,1-diphenyl hydrazone; and said phosphorus-containing lubricant is an acidic phosphate amine salt which is a reaction product of an amine and an acidic phosphate, wherein said amine is a primary or secondary amine having a hydrocarbon group of from about 6 to about 20 carbon atoms, and said acidic phosphate is selected from the group consisting of dibutyl acid phosphate, dihexyl acid phosphate, di-2-ethylhexyl acid phosphate, didecyl acid phosphate, didodecyl acid phosphate, tridecyl acid phosphate, dioctadecyl acid phosphate, di-9-octadecenyl acid phosphate, and lauryl acid phosphate.
