ABSTRACT:
A charge transport layer composition for a photoreceptor includes at least a binder and a charge transport material of about 100% to about 40% by weight of a total of the charge transport layer N,N-dimethylphenyl)-4-biphenylamine and about 0% to about 60% N,N′-dephenyl-N,N′-bis(3-methylphenyl)-(1,1′-biphenyl)-4,4′-diamine, and wherein the total charge transport material in the composition is 48% or less of the total solids of the composition. The charge transport layer forms a layer of a photoreceptor, which also includes an optional anti-curl layer, a substrate, an optional hole blocking layer, an optional adhesive layer, a charge generating layer, and optionally one or more overcoat or protective layers.
