Abstract
An electrophotographic photoreceptor has excellent electrical properties and is stable even upon repeated use. An electrophotographic apparatus using the electrophotographic photoreceptor uses a compound having an excellent electron transporting ability in a photosensitive layer of the electrophotographic photoreceptor. An electrophotographic photoreceptor, in which a photosensitive layer is located on an electrically conductive substrate either directly or via an undercoat layer, contains a compound having a structure represented by the general formula (I).An electrophotographic apparatus contains the above-mentioned electrophotographic photoreceptor, and carries out a charging process through a positive charging process.
