Claims

[Claims for Utility Model Registration] 1. A Kob9 ion generator that is opposed to a discharge target and generates corona ions using a discharge wire, and a shield that can be inserted between the corona ion generator and the discharge target. 1. A corona ion discharger comprising: a member; and a power source that applies a bias voltage to the shield member that is the same as the potential of an equipotential surface of a space where the shield member is located when the shield member is inserted. 2. The corona ion discharger according to claim 1, wherein the minimum radius of curvature at any position of the shielding member is larger than the radius of the discharge wire. 3. The corona ion discharger according to claim 1 or 2 of the utility model registration, characterized in that the power source of the corona ion generator is a constant current power source.
