Abstract
An electrophotographic apparatus including an electrophotographic photosensitive member, a charging unit that charges a surface of the electrophotographic photosensitive member, an exposing unit that irradiates the charged surface of the electrophotographic photosensitive member with light to form an electrostatic latent image on the surface of the electrophotographic photosensitive member, and a developing unit, which includes toner, and which develops the electrostatic latent image formed on the surface of the electrophotographic photosensitive member with the toner to form a toner image on the surface of the electrophotographic photosensitive member. The electrophotographic photosensitive member includes a monolayer type photosensitive layer containing a charge generating substance, a hole transporting substance, an electron transporting substance, and a binder resin. The photosensitive layer contains, as the binder resin, a polyarylate resin having a structural unit represented by the following formula (1) and a structural unit represented by the following formula (2).
