Abstract

A corona discharger includes a shield and a discharge wire extended between opposed ends of the shield and supported between its ends. The position of the wire is adjustable to control the distance between the wire and a surface of a member to be subjected to the corona discharge and a spring is arranged to maintain tension on the discharge wire regardless of the position of adjustment of the wire.
