摘要： An electrophotographic apparatus is disclosed using an electrophotographic photosensitive member which employs light with a short wavelength (380 nm to 500 nm) as image exposure light and is good in photoelectric conversion efficiency on the whole at that wavelength. The electrophotographic photosensitive member is composed of a reflecting layer, a charge generation layer and a charge transport layer formed on a support. The total reflectance and specular reflectance of the reflecting layer are 30% or more (with respect to a standard white board) and less than 15%, respectively, at that short-wavelength light. The absorbance of the charge generation layer is 1.0 or less at that short-wavelength light.
