PURPOSE:To form stable electric fields with accelerated ionization and improved counter electrode efficiency by providing an electrostatic charging electrode and an electric field electrode in the opening part of a spray nozzle, and providing a counter electrode of a projecting shape in the position near the electric field electrode. CONSTITUTION:An electrostatic charging electrode 24 which receives the supplies of high voltage and discharges electrostatic charge, an electricity receiving electrode 26 which receives the discharge from the electrode 24 by crossing the paint films sprayed from a nozzle port 20, and a floating electrode 25 of an electric field electrode 27 which extends forward from the electrode 26 are provided at the preceding spraying part. Further, a projecting part 14a which concentrates electric fields is formed as a counter electrode in the position, such as a gun handle part 14 or the like as near the electrode 27 as possible. Sprayed paint is accelerated of ionization by the discharge from the electrode 24 to the electrode 25. The electrode 25 forms the stable electric fields between the projecting part 14a of the counter electrode and a substrate, thus providing a much stable electrostatic effect. |
