Abstract
A triarylamine derivative is represented by general formula (I). In 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. In general formula (I), m and n each represent an integer of at least 0 and no greater than 4. When m and n represent integers greater than 1, chemical groups R1 bonded to the same aromatic ring and chemical groups R2 bonded to the same aromatic ring may be the same or different to one another.
