Patent ID: 7202004

Claim:
An electrophotographic imaging process comprising: (a) applying an electrical charge to a surface of an organophotoreceptor comprising: (i) a charge transport compound having the formula where n is an integer between 2 and 6, inclusive; R 2 is a sulfolanyl group; a pyrrolyl group; a tetrazolyl group; a benzotriazolyl group; a stilbenyl group; an alkylsulfonylphenyl group, an arylsulfonylphenyl; a pyrazolyl group; or group A, wherein A is represented by the formula R 1 may be hydrogen, an alkyl group, or an aryl group with the proviso that when R 2 is a sulfolanyl group, a pyrrolyl group, a tetrazolyl group, a benzotriazolyl group, the group A, a stilbenyl group, or a pyrazolyl group, R 1 is an aryl group; X is an alkylene linking group having the formula —(CH 2 ) m —, where m is an integer between 0 and 20, inclusive, and one or more methylene groups in the alkylene group is optionally replaced by an oxygen atom, a carbonyl group, urethane, urea, an ester group, a —NR 3 , group, a CHR 4 group, or a CR 5 R 6 group where R 3 , R 4 , R 5 , and R 6 are, independently, H, an alkyl group, or aryl group; and Y is a bond, carbon atom, nitrogen atom, oxygen atom, sulfur atom, a —(CH 2 ) p — group where p is an integer between 0 and 10, an aryl group, a cycloalkyl group, a cyclosiloxyl group, a heterocyclic group, or a CR 7 group where R 7 is hydrogen atom, an alkyl group, or aryl group; (ii) a charge generating compound; and (iii) an electrically conductive substrate; (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 liquid toner comprising a dispersion of colorant particles in an organic liquid to create a toned image; and (d) transferring said toned image to a substrate.
