POTENTIAL CONTROLLER AND IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a potential controller and an image forming device capable of realizing uniform and stable electrification or transfer and obtaining stable image quality over a long term regardless of atmospheric temperature and humidity and the soiling and the wear of an image carrier. SOLUTION: An image forming condition influencing an image formed on paper 10 finally is controlled based on the result of measurement at the time of applying measuring voltage obtained by applying the measuring voltage below or near electrification start voltage between an electrifying device 2 electrifying a photoreceptor l in contact with the surface of the photoreceptor 1 and the photoreceptor 1 to the device 2 by a power source 3.
