A device for cleaning a corona wire of a corona discharger which is installed in an electrophotographic copier, electrostatic printer or similar electrostatic recorder to play the role of a charger or a discharger. Cleaning members each being provided with a cleaner pad for rubbing against the corona wire are driven by a feed screw and not by a wire and pulley mechanism. The cleaning members brought to a home position are fully spaced apart from the corona wire. When cleaner support members are brought close to any of members which journal the feed screw at opposite ends of the feed screw, they are caused into resilient contact with the journalling member through a coil spring.
