PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which causes no fog by local charging failure in any environment or not only in the initial stage but in a long-term period, which stably maintains the potential for repeated use in any environment, which exhibits stable image characteristics without depending on the use environment such as temperature and humidity, which has high sensitivity and which is easily manufactured, and to provide a process cartridge and an electrophotographic device equipped with the above photoreceptor. SOLUTION: The electrophotographic photoreceptor features that: an intermediate layer containing an electron transfer organic compound and a photosensitive layer containing a charge generating material are successively formed in this order on a support; the intermediate layer has≥0.3μm and≤3μm film thickness; the photosensitive layer has≤16μm film thickness; and the energy level of the highest occupied molecular orbital (HOMO) of the electron transporting organic compound is≥6.0 eV. The process cartridge and the electrophotographic device are equipped with the above electrophotographic photoreceptor. COPYRIGHT: (C)2004,JPO |
