    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: 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.

    Abstract: An electrophotographic photosensitive member includes a conductive substrate and a photosensitive layer. The photosensitive layer is a single-layer photosensitive layer and contains a charge generating material, a hole transport material, an electron transport material, and a binder resin. A hole mobility μh is at least 1.00×10−7 cm2/V/second and an electron mobility μe is at least 4.00×10−8 cm2/V/second in the photosensitive layer as measured under conditions of a temperature of 23° C. and an electric field intensity of 1.50×105 V/cm. A ratio (μh/μe) of the hole mobility μh to the electron mobility μe is at least 1.0 and no greater than 50.0.
