ABSTRACT:
A photoconductive imaging member comprised of a supporting substrate, an inorganic photogenerating layer, or a photogenerating layer comprised of metal free phthalocyanines, metal phthalocyanines, vanadyl phthalocyanines, squaraines, perylenes, or dibromoanthrone; and a charge transport layer comprised of N,N-bis(biarylyl)aniline compounds of Formula (I) or tris(biarylyl)amine compounds of Formula (II), wherein R, R', R" are independently selected from the group consisting of hydrogen, halogen, alkyl, aryl, alkoxy, and alkoxycarbonyl, and x, y, and z are the numbers 0, 1, or 2. Examples of charge transport compounds include N,N-bis(4-biphenylyl)-3,5-dimethoxyaniline (Ia); N,N-bis(4-biphenylyl)-3,5-dimethylaniline (Ib); N,N-bis(4-methyl-4'-biphenylyl)-3-methoxyaniline (Ic); N,N-bis(4-methyl-4'-biphenylyl)-3-chloroaniline (Id); N,N-bis(4-bromo-4'-biphenylyl)-3,5-dimethoxyaniline (Ig); 4-biphenylyl bis(4-ethoxycarbonyl-4'-biphenylyl)amine (IIa); 4-biphenylyl bis(4-acetoxymethyl-4'-biphenylyl)amine (IIb); or 4-ethoxycarbonyl-4'-biphenylyl bis(4-methyl-4'-biphenylyl)amine(IId).
