Triarylamine derivative and electrophotographic photosensitive member

A triarylamine derivative represented by general formula (I)

• where, in the general formula (I),
• R1 and R2 each represent, independently of one another, a chemical group selected from the group consisting of a halogen atom, an optionally substituted alkyl group having a carbon number of at least 1 and no greater than 6, an optionally substituted alkoxy group having a carbon number of at least 1 and no greater than 6, and an optionally substituted aryl group having a carbon number of at least 6 and no greater than 12,
• m and n each represent an integer of at least 0 and no greater than 4,
• when m represents an integer greater than 1, chemical groups R1 bonded to the same aromatic ring may be the same or different to one another, and
• when n represents an integer greater than 1, chemical groups R2 bonded to the same aromatic ring may be the same or different to one another.
