Abstract
At least two sets of ion-generating means are provided to face each other through a space having an insulating sheet. The first and second surfaces of the sheet are simultaneously irradiated with monopolar ion clouds substantially opposite to each other in polarity generated from the ion-generating means. The sheet is subsequently irradiated with monopolar ion clouds reverse in polarity to that of the previously applied ion clouds, to eliminate the positive and negative charges of both the surfaces of the insulating sheet.
