(57) [Problem] To provide an electrophotographic photosensitive member satisfying all of high sensitivity, high image quality and high resolution, and an electrophotographic apparatus using the same. SOLUTION: In an electrophotographic photosensitive member having a conductive support 2, an undercoat layer 3 formed on the conductive support, and a photosensitive layer 4 formed on the undercoat layer, the undercoat layer 3 is made of titanium oxide. The photosensitive layer 4 contains particles and has a Bragg angle (2θ ± 0.2 °) of at least 7.0 ° or 7.6 ° in an X-ray diffraction spectrum with respect to CuKα characteristic X-rays (wavelength: 1.54 °). , 9.0 °, 13.6 °, 16.8 It contains a crystalline phthalocyanine composition with peaks at ° and 27.2 °. |
