Abstract

A discharge device for generating a corona discharge aimed at an object facing the discharge device, the discharge device comprising: a plate-like main discharge electrode configured to receive an applied direct current voltage and generate the corona discharge aimed at the object; a plate-like auxiliary discharge electrode disposed in parallel with the main discharge electrode and configured to receive an applied direct current voltage which is opposite in polarity to the applied direct current voltage received by the main discharge electrode, thereby causing the corona discharge to occur between the main discharge electrode and the auxiliary discharge electrode; and a plate-like insulating member disposed between the main discharge electrode and the auxiliary discharge electrode, wherein the insulating member is disposed in such a manner that a discharge current from the main discharge electrode flows to both the object and the auxiliary discharge electrode.
