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), R 1 represents an alkyl group having a carbon number of at least 2 and no greater than 4. R 2 , R 3 , R 4 , R 5 , and R 6 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. Ar 1 and Ar 2 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 Ar 1 and Ar 2 represents an optionally substituted aryl group having a carbon number of at least 6 and no greater than 20. |
