Patent ID: 7026089

Claim:
An electrophotographic imaging process comprising: (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; R 1 and R 2 are, independently, hydrogen, a branched or linear alkyl group, a branched or linear unsaturated hydrocarbon group, an ether group, a cycloalkyl group, or an aryl group; X is a bis(fluorene-4-carboxyl)alkane group; Y is a divalent sulfonyldiphenylene group; Z is X═O where X is double-bonded to the adjacent N or two hydrogens where each hydrogen is independently single-bonded to the adjacent N; and Q is O or N—N(R 1 )—Y—N(R 2 )—NH 2 ; (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.
