Abstract

PURPOSE:To enable control after the disconnection of a power source without clocking the OFF time of the power source, by making a photosensitive body grow weary once completely immediately after applying the power source. CONSTITUTION:To a microcomputer 20 which controls the static elimination lamp 27 of a photosensitive drum, a ROM 21 in which a control program and a duty factor table are stored, counters A-C, and a RAM 22 on which a flag and a timer are set are connected. And the photosensitive drum is rotated for several minutes to warm up every image forming process part immediately after a power switch is turned on, and by projecting static elimination light with 100% of light quantity (full duty) during the rotation of the drum, the photosensitive body can grow weary completely. Therefore, it is enough to perform correction hereafter based on a recovery characteristic from a complete fatigue state, and it is not required to consider a state before applying the power source. In such a way, it is possible to maintain the surface potential of the photosensitive body constant even in a consecutive operation, or after a long pause time.
