Abstract

A photoconductive imaging member comprised of a photogenerating layer, and a charge transport layer comprised of diaryl biarylylamine copolymers of the formula ##STR1## wherein A and B are independently selected from bifunctional linkages; Z is alkylenedioxy, arylenedioxy, or substituted derivatives thereof; R and R' are alkyl, aryl, substituted alkyl, substituted aryl, alkoxy, or halogen; x and y are mole fractions wherein x and y are greater than 0 and the sum of x and y is equal to 1.0; a and b are the numbers 0, 1 or 2; and n represents the number of monomer segments.
