PURPOSE: To prevent cracks in repeated use for a long time, contamination of the base due to scraping of a film, and production of image defects from occurring by forming a photosensitive layer containing bisphenol-Z polycarbonate and having a specified glass transition temp. CONSTITUTION: When the photoreceptor has a single layer structure, a photosensitive layer 2 prepared by dissolving or dispersing a charge producing material and a charge transfer material in a binder resin is formed on a conductive base body 1. The photosensitive layer 2 contains a bisphenol-Z type polycarbonate and >=85 deg.C glass transition temp. As for the conductive supporting body 1, a material having <=10<10>Ωvolume resistivity is used, and for example, a body produced by depositing an oxide of aluminum or the like on an endless-belt plastic material by vapor deposition or sputtering is used. The photosensitive layer 2 is formed by dissolving a charge producing material such as metal phthalocyanine, a charge transfer material such as chloranil, and a binder resin such as bisphenol-Z polycarbonate in a solvent, and then applying the liquid and drying.
