Abstract
There is provided an electrophotographic photoreceptor whose surface layer does not easily become thin in use of the electrophotographic photoreceptor, so that occurrence of image defects such as image non-uniformity can be avoided. An electrophotographic photoreceptor includes a cylindrical substrate; a photosensitive layer formed on the cylindrical substrate, the photosensitive layer including at least a photoconductive layer; and a surface layer formed on the photosensitive layer. The surface layer contains amorphous carbon, and has a ratio of an integrated intensity of D band to an integrated intensity of G band in a Raman spectrum of the surface layer being 0.86 or higher and 1.23 or lower. There is realized an electrophotographic photoreceptor whose surface layer does not easily become thin in use of the electrophotographic photoreceptor, so that occurrence of image defects such as image non-uniformity can be prevented.
