This invention relates to a novel electrophotographic imaging process that includes: (a) applying an electrical charge to a surface of an organophotoreceptor comprising: (i) a charge transport composition comprising molecules having the formula where the average n is between 1 and 1000; R1 and R2 are, independently, hydrogen, alkyl, unsaturated hydrocarbon, ether, cycloalkyl, or aryl; X is a bis(fluorene-4-carboxyl)alkane group; Y is a sulfonyldiphenylene; Z is X=O or two hydrogens; and Q is O or N—N(R1)—Y—N(R2)—NH2; (ii) a charge generating compound; and (iii) an electrically conductive substrate over which said charge transport composition and said charge generating compound are located; (b) imagewise exposing said surface of said organophotoreceptor to radiation to dissipate charge in selected areas and thereby form a pattern of charged and uncharged areas on said surface; (c) contacting said surface with a toner to create a toned image; and (d) transferring said toned image to a substrate.
