A coronode for use in an electrophotographic apparatus has one end thereof coupled to a high electrical potential output of an electrical transformer for use in generating a corona discharge current. A tap from another terminal of the transformer is coupled to another end of the coronode to establish a small EMF between the ends of the wire that is used in resistance heating of the coronode.
