Abstract
An apparatus which forms a discharge electric field in order to discharge an object. The apparatus includes an electrode member facing and separated by a preselected gap from the object, and a power source which applies a discharge voltage to the electrode member to thereby cause discharge to occur between the object and the electrode member. Further, the electrode member at the gap includes a material selected in association with the gap so that a functional relationship between the discharge voltage and a discharge current caused by the discharge voltage is a continuous function.
