とができる。According to the present invention, the discharge electrode of the electrostatic charging device is supported by the hollow insulator and is insulated from the ground portion. Then, the air heated by the heating means is supplied into the insulator by the air supply means. Since the insulator is heated by supplying the heated air, even if moisture such as fog or snow adheres, the adhered water can be dried. Therefore, since the supporting portion of the discharge electrode can always maintain a dry state, it is possible to ensure insulation from the ground portion. The air supplied to the insulator is detected by a first temperature detector that detects the temperature of the air flowing into the electrostatic charging device by the control means and a second value that detects the temperature of the air flowing into the heating means. By comparing the detected value of the second temperature detector with the detected value of the temperature detector, the heating means is activated when the detected value of the second temperature detector is lower than the detected value of the first temperature detector. Thus, the energy saving operation can be ensured by operating the heating means only when the air flowing into the heating means is lower than the air flowing into the electrostatic charging device.

Even if moisture such as snow or fog adheres to the support portion of the discharge electrode, the attached moisture can be efficiently removed, so that the support portion of the discharge electrode and the ground portion can be effectively insulated. it can.
As a result, the leak current in the high voltage section can be reduced and the electric power can be effectively used. Further, since the insulation of the high-voltage portion is improved, the voltage applied to the electrostatic charging device can be increased and the electrostatic charging device can be operated. Therefore, the performance of the electrostatic charging device can be improved.
