Based on difference between the detected electrostatic charge potential and a time required for rotating the drum 2 by prescribed times, the dark decay a characteristic of the drum 2 is detected. Based on the detected dark decay characteristic and the disposing distances of the respective developing devices, the dark decay quantity extending over the respective developing devices is estimated after the surface 2a is electrostatically charged. Based on the estimated quantity, a look-up table or the like is switched by a tone correction means 40 in every developing device and tone is corrected. Then, the excellent halftone is always reproduced even when the photosensitive characteristic is changed.
