Organophotoreceptor with an epoxy-modified charge transport compound having an azine group

An electrophotographic imaging apparatus comprising:

• (a) a light imaging component;
• and
• (b) an organophotoreceptor oriented to receive light from the light imaging component, the organophotoreceptor comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising
• (i) a charge transport compound having the formula
• where R1 and R2 are, independently, hydrogen, an alkyl group, a heterocyclic group, an alkaryl group or an aryl group;
• X is an aromatic group;
• Y is an (N,N-disubstituted) arylamine group;
• Z is (CH2)m group where m is an integer between 1 and 30 where one or more of the methylene groups is optionally replaced by O, S, C═O, O═C—O, O═C—NR3, sulfoxide, sulfate, phosphate, an aryl group, urethane, urea, a NR4 group, a CHR5 group, or a CR6R7 group where R3, R4, R5, R6, and R7 are, independently, H, hydroxyl, thiol, an amine group, an alkyl group, a heterocyclic group, an alkaryl group, or an aryl group, and E is an epoxy group;
• and
• (ii) a charge generating compound.

An electrophotographic imaging process comprising:

• (a) applying an electrical charge to a surface of an organophotoreceptor comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising
• (i) a charge transport compound having the formula
• where R1 and R2 are, independently, hydrogen, an alkyl group, a heterocyclic group, an alkaryl group or an aryl group;
• X is an aromatic group;
• Y is an (N,N-disubstituted) arylamine group;
• Z is (CH2)m group where m is an integer between 1 and 30 where one or more of the methylene groups is optionally replaced by O, S, C═O, O═C—O, O═C—NR3, sulfoxide, sulfate, phosphate, an aryl group, urethane, urea, a NR4 group, a CHR5 group, or a CR6R7 group where R3, R4, R5, &, and R7 are, independently, H, hydroxyl, thiol, an amine group, an alkyl group, a heterocyclic group, an alkaryl group, or an aryl group, and E is an epoxy group;
• and
• (ii) a charge generating compound;
• (b) imagewise exposing the surface of the organophotoreceptor to radiation to dissipate charge in selected areas and thereby form a pattern of charged and uncharged areas on the surface;
• (c) contacting the surface with a toner to create a toned image;
• and
• (d) transferring the toned image to a substrate.
