CHARGE TRANSPORT MATERIAL, ORGANOPHOTORECEPTOR INCLUDING CHARGE TRANSPORT MATERIAL, ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS INCLUDING ORGANOPHOTORECEPTOR, AND ELECTROPHOTOGRAPHIC IMAGE FORMING METHOD USING ORGANOPHOTORECEPTOR

摘要

PROBLEM TO BE SOLVED: To provide a charge transport material having excellent electrostatic properties, an organophotoreceptor with the charge transport material, an electrophotographic image forming apparatus with the organophotoreceptor, and an electrophotographic image forming method using the organophotoreceptor. SOLUTION: The organophotoreceptor comprises an electrically conductive substrate and a photoconductive element located on the electrically conductive substrate, wherein the photoconductive element comprises the charge transport material having formula 1 and a charge generating compound. In the formula 1, n is an integer of 2-6; R1and R2are, independently, H, an alkyl group, an alkaryl group or an aryl group; X is a linking group having a structure of the formula -(CH2)m-; Y comprises a bond, C, N, O, S, -(CH2)p-, an aromatic group, a cycloalkyl group, a heterocyclic group or a NR7group; and Z comprises a heterocyclic group selected from the group consisting of phenothiazine group, phenoxazine group, phenoxathiin group, dibenzo(1,4)dioxin group, thianthrene group and phenazine group.
