Abstract
An atomizer () with a rotary atomizing head () is mounted on the front side of a housing member () in which an air motor () is accommodated. A primary external electrode () is located around the outer peripheral side of the housing member () in such a way as to encircle the housing member (). A secondary external electrode () is located on the front side of the housing member (), in a position closer to the rotary atomizing head () than the primary external electrode (). A first high voltage (V) in the form of a direct-current voltage is supplied to the primary external electrode () from a first high voltage generator (). On the other hand, a second high voltage (V), in the form of a pulsating voltage (V) consisting of a series of intermittent pulses in a range lower than the first high voltage (V), is supplied to the secondary external electrode () from a second high voltage generator ().
