    Abstract: A triphenylamine derivative is represented by general formula (1). In general formula (1), R1 to R7 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. Also, k, l, m, n, o, and p each represent, independently of one another, an integer of at least 0 and no greater than 4. When any of k, l, m, n, o, or p represents an integer greater than 1, chemical groups R3, R4, R5, R6, or R7 bonded to the same aromatic ring may be the same or different.

    Abstract translation: 三苯胺衍生物由通式（1）表示。 通式（1）中，R 1〜R 7各自独立地表示选自卤素原子，碳数为1以上且6以下的任意取代的烷基的化学基团， 碳数为至少为1且不大于6的任选取代的烷氧基，以及碳原子数为6以上且12以下的任意取代的芳基。另外，k，l，m，n，o 和p各自独立地表示至少为0且不大于4的整数。当k，l，m，n，o或p中的任一个表示大于1的整数时，化学基团R 3，R 4 键合到相同芳环的R 5，R 6或R 7可以相同或不同。

    Abstract: In a positively chargeable single-layer electrophotographic photosensitive member, a photosensitive layer contains at least a hole transport material, and particles of a first resin. A compound represented by general formula (1) is contained as the hole transport material. In the general formula (1), R1 represents an alkyl group having a carbon number of at least 2 and no greater than 4. R2, R3, R4, R5, and R6 each represent, independently of one another, a hydrogen atom or an alkyl group having a carbon number of at least 1 and no greater than 4. Ar1 and Ar2 each represent, independently of each other, a hydrogen atom or an optionally substituted aryl group having a carbon number of at least 6 and no greater than 20. At least one of Ar1 and Ar2 represents an optionally substituted aryl group having a carbon number of at least 6 and no greater than 20.

    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 1-6, an optionally substituted alkoxy group having a carbon number of 1-6, and an optionally substituted aryl group having a carbon number of 6-12. In general formula (I), k and l each represent an integer of at least 0 and no greater than 4. When k and l 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. In general formula (I), m and n each represent a different integer of at least 1 and no greater than 3.
