Abstract
An atomizer including an air motor and a rotary atomizing head is mounted in a front side of a housing member, outer surfaces of which are covered in a cover member. Further, a high voltage discharge electrode assembly is provided around a front side of the housing member, with an outer periphery of the cover member circumvented by a blade ring of the high voltage discharge electrode assembly. An edge portion in the shape of a thin blade is provided at a projected rear end of the blade ring. Thus, an electric field is concentrated at the edge portion to induce a corona discharge on and around the entire blade ring.
