<p>Disclosed is an electrophotographic photosensitive body having a photosensitive layer on a conductive base. This electrophotographic photosensitive body is characterized in that at least the outermost layer thereof contains particles having a double structure composed of a core member and a shell member having a lager rubber hardness than the core member. This electrophotographic photosensitive body exhibits excellent mechanical strength such as wear resistance, abrasion resistance and scratch resistance as well as excellent electrophotographic characteristics such as cleaning properties for a long time.</p>
