Abstract

PURPOSE:To miniaturize a boosting transformer and to reduce a generating quantity of ozone by specifying relation between the time of one period of a voltage waveform to generate the corona discharge of AC voltage to be impressed on a discharge element and the time of the period to repeat the voltage waveform. CONSTITUTION:The AC voltage Vac is supplied so that an AC voltage waveform to generate the corona discharge of period (t) can be repeated intermittently at a repetitive period T. When the corona discharge is generated by the AC voltage waveform W, ion with positive and negative polarity are generated in the neighborhood of a discharge electrode 3, and only he ion with specific polarity, for example, the ion with negative polarity is attracted to the surface of a body 5 to be electrified by a bias voltage impressed between the body 5 to be electrified and the discharge element 1, and an electrifying current Ic flows. And the time (t) of one period of the voltage waveform to generate the corona discharge of AC impression voltage and the time T of the repetitive period of the voltage waveform are set so as to be set as (t)<T. In such a way, the generating quantity of the ozone can be reduced, and unevenness in electrification can be eliminated, and a power source can be miniaturized.
