CHARGE TRANSPORT MATERIAL, ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a charge transport material which has high sensitivity, can make a high-speed response, and can maintain high image quality even in repetitive use when applied to an electrophotographic photoreceptor. SOLUTION: The charge transport material is represented by formula (1) wherein X1and X2each independently denote a group represented by formula (2); p and q each independently denote an integer of 1-5; R1and R2each independently denote H, a 1-4C substituted or unsubstituted alkyl or a 1-4C substituted or unsubstituted alkoxy; R3denotes H, a 1-4C substituted or unsubstituted alkyl or a 1-4C substituted or unsubstituted alkoxy; k1 and k2 each independently denote an integer of 0-4; k3 denotes an integer of 1-4; and X3denotes a monovalent organic group. In the formula (2), X4-X6each independently denote a 1-6C substituted or unsubstituted hydrocarbon group or a substituted or unsubstituted aromatic group, and at least two or X4-X6may form a ring.
