A benzidine derivative, a method for producing benzidine derivative, and an electrophotographic photosensitive member. The benzidine derivative is represented as the general formula (1), wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10 and R11 are independent from each other and represent hydrogen atom, halogen atom, optionally substituted alkyl group being more than 1 and less than 6 in carbon atom number, optionally substituted alkoxy group being more than 1 and less than 6 in carbon atom number, and optionally substituted aryl group being more than 6 and less than 14 in atom number, n being an integer being more than 0 and less than 2.
