Abstract

In a pair of surface-shaped silent discharge electrodes opposed to each other and separated by a predetermined space, phases of alternating voltages are applied to the respective silent discharge electrodes shifted in phase with respect to each other. Thus, a silent discharge may arise alternately on either one of the electrode surfaces. A second alternating voltage is applied between the silent discharge electrodes and is alternatingly varied at a frequency twice as high as the frequency of the first alternating voltages. Powder particles are passed through the space which separates the pair of surface-shaped silent discharge electrodes and charged in either positive or negative polarity.
