A multi-layer electrophotographic photosensitive member contains a charge generating material including oxo-titanium phthalocyanine that among diffraction peaks for Bragg angles 2&thetas;±0.2° with respect to characteristic X-rays of CuKα having a wavelength of 1.542 Å, at least exhibits a highest diffraction peak at 27.2°. The multi-layer electrophotographic photosensitive member also contains a hole transport material including a triarylamine derivative shown in Generic Formula (1). A ratio of the hole transport material relative to a binder resin in a charge transport layer is no greater than 0.55. In Generic Formula (1), Ar1 represents an aryl group substituted with at least one substituent selected from the group consisting of an alkoxy group having two to four carbon atoms and an optionally substituted phenoxy group, and Ar2 represents an aryl group optionally substituted with an alkyl group having one to four carbon atoms.
