Abstract
A discharging device includes first and second electrodes sandwiching therebetween a dielectric member, wherein an alternating voltage is applied between the first electrode and the second electrode to produce electric discharge adjacent to the second electrode. The relation between the alternating voltage and a distance between an end surface of the second electrode to a corresponding end of a region where the electric discharge occurs, is so determined that an intermediate saturation property is exhibited. The level of the alternating voltage is set to provide the intermediate saturation property. With such a discharging device, a member is electrically charged or discharged.
