ABSTRACT:
A charger charges a body with a voltage in which an AC voltage is superimposed on a DC voltage. The charger and the body have a small gap therebetween. A sensor measures a humidity in the gap between the charger and the body. A magnitude of the AC voltage to be superimposed on the DC voltage is determined based on the humidity detected.
