PROBLEM TO BE SOLVED : To provide a conductive support, an electrophotographic photoreceptor using the conductive support, an electrophotographic cartridge, and an image forming apparatus, capable of reducing vibration of the electrophotographic photoreceptor and preventing abnormal sound from occurring, without adding a member such as a vibration control member. SOLUTION : A conductive support includes mainly aluminum and at least one of nickel and a rare-earth element. When a surface of the conductive support is observed by magnifying it 500 times with a scan type electron microscope, the average number per unit area of at least one of an intermetallic compound based on the aluminum and the nickel and an intermetallic compound based on the aluminum and the rare-earth element is not less than 0.005 pieces/μm2 and not more than 0.1 pieces/μm2. Further, there are provided an electrophotographic photoreceptor using the conductive support, an electrophotographic cartridge, and an image forming apparatus. COPYRIGHT : (C)2013, JPO&INPIT
