Abstract
A triphenylamine derivative is represented by general formula (1). In the general formula (1): R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 each represent, independently of one another, a hydrogen 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, an optionally substituted alkenyl group having a carbon number of at least 2 and no greater than 6, or an optionally substituted aryl group having a carbon number of at least 6 and no greater than 14; m represents an integer of at least 1 and no greater than 3; and n represents an integer of at least 0 and no greater than 2.
Claims3
An electrophotographic photosensitive member comprising a conductive substrate and a photosensitive layer, wherein
- the photosensitive layer contains at least a charge generating material and the triphenylamine derivative represented by general formula (1) shown below as a hole transport material:
- where, in the general formula (1), R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 each represent, independently of one another, a hydrogen 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, an optionally substituted alkenyl group having a carbon number of at least 2 and no greater than 6, or an optionally substituted aryl group having a carbon number of at least 6 and no greater than 14,
- m represents 2, and
- n represents an integer of at least 0 and no greater than 2.
