PURPOSE:To enhance electrophotographic characteristics and durability of a photosensitive body by forming a protective layer containing an electric charge generating organic pigment. CONSTITUTION:The photosensitive body is formed by successively laminating on a conductive substrate a charge transfer layer containing an electron receptive charge transfer material, a charge generating layer containing an organic pigment (a), preferably such as one or more of tau, tau', eta' and eta-type metal-free phthalocyanines, and the protective layer (A) containing the organic pigment (b), such as a desired pigment containing said phthalocyanine, dispersed into an insulating resin (c), preferably such as a butylated melamine.formaldehyde resin (a) having a number average molecular weight of <=1,500, a bonded formaldehyde number of 2-4 and a methylol number of 1 or 2 per one melamine ring. |
