(57) [Summary] [Purpose] Laminated electrophotographic photosensitive material that does not have residual potential rise due to photodegradation, deterioration of sensitivity and chargeability even after repeated use, and has good abrasion resistance and high durability. Provide the body. A laminate type electrophotographic photoreceptor having a photosensitive layer comprising at least a charge generating layer and a charge transfer layer on a conductive substrate, wherein the charge generating layer contains an asymmetric disazo pigment as a charge generating substance. A photoconductor for electrophotography, characterized in that a compound (for example, an organic phosphite compound, a thioether compound, etc.) that prevents photooxidation of a charge generating substance is present therein. |
