A CPU 26 sets the value of the applied voltage to a first set value when the absolute value of the amount of charge on the toner remaining on the intermediate transfer belt 8 is lower than a threshold value, and sets the value of the applied voltage to a second set value when the absolute value of the amount of charge on the toner remaining on the intermediate transfer belt 8 is equal to or greater than the threshold value, and when the first set value is VC1 and the second set value is VC2, the relationship |VC1|
