ABSTRACT:
A device for electrically discharging or charging a member to be discharged or charged, includes a dielectric member, first and second electrodes embedded in the dielectric member, the first and second electrodes being supplied with an alternating voltage therebetween to cause discharge adjacent a part of a surface of the dielectric member at a predetermined discharge starting voltage, a third electrode disposed to or adjacent a part of the surface of the dielectric member at such a position as when the discharge occurs by application of the alternating voltage between the first and second electrodes, no discharge occurs between the first electrode and the third electrode or between the second electrode and the third electrode, AC source for applying an alternating voltage between the first electrode and the second electrode, DC source for applying a bias voltage between the third electrode and the member to be discharged or charged.
