Besides, the value of |VD-V2| is calculated, based on the electrifying potential VD being the measured result and the potential V2 of the second potential part of the AC voltage of the present developing bias. By previously deciding the reference value of |VD-V2| for preventing the carrier from being attached and controlling the output of a power source 10 by the control means 21 so that the value of |VD-V2| always becomes the reference value, the duty ratio of the AC voltage component of the developing bias and a DC voltage value are changed.
