Abstract
Disclosed is an electrophotographic photosensitive body which does not cause image defects such as black spots and image unevenness when image exposure is performed using light having a wavelength of 350-500 nm, which is so-called short-wavelength light. The electrophotographic photosensitive body is characterized by having at least an intermediate layer, a charge-generating layer containing a metal phthalocyanine pigment and a charge-transporting layer on a conductive supporting body which has a skewness of the profile (Rsk) within the range of −8<Rsk<0.
