Abstract
There is disclosed in an IOI system which predicts surface potentials of a photosensitive drum positioned in developing positions of individual developing devices from detection results of the surface potentials by two surface potential sensors per developing device, disposed before/after the developing device of each of the plurality of image forming units before/after expose and which controls a charging device in such a manner that a predicted value of the surface potential before the expose indicates a defined developing reference value and which controls an exposing device in such a manner that the predicted value of the surface potential after the expose indicates a defined expose reference value. The image forming units of second and subsequent colors, a charging amount by the charging device is controlled in consideration of charging histories by the charging devices of previous colors.
