Abstract
There is disclosed a corona discharger comprising a discharge wire for producing a corona discharge, a voltage source for applying a predetermined voltage to the discharge wire, an electrically conductive back plate being provided on the opposite side of the discharge wire to a member to be electrified, and an electrically conductive side plate being provided close to the member to be electrified. In the corona discharger, an opening for discharging ozone produced by said corona discharge is formed between said side plate and said back plate, and respective electric potentials of the side plate and the back plate are set so that a difference between respective electric potentials of the side plate and the discharge wire becomes lower than a difference between respective electric potentials of the back plate and the discharge wire.
