Electrophotographic photoreceptor, method of preparation, and electrophotographic imaging apparatus |
摘要 |
An electrophotographic photoreceptor includes a photosensitive layer including a charge generating material, a charge transporting material and a binder resin in a single layer, formed on an electrically conductive substrate. The single photosensitive layer includes an upper photosensitive layer portion and a lower photosensitive layer portion. The upper photosensitive layer portion has a higher concentration of the electron transporting material than that of the lower photosensitive layer portion. A method of preparing the electrophotographic photoreceptor, and an electrophotographic imaging apparatus employing the electrophotographic photoreceptor are provided. The single-layered type electrophotographic photoreceptor according to the present invention shows high sensitivity and excellent repetition stability of electrical properties, while still having advantages of a conventional single-layered photoreceptor, thereby being able to have highly practical applications.
