A triboelectric powder spraying gun is provided which can produce an increased deposition efficiency and an improved coated surface. The spraying gun comprises an earthed or high voltage-impressed conductive nozzle having, as a lining, a plastic material which possesses an electrification series remarkably different from that of a powdered paint, in which said powdered paint is transferred to said nozzle so that it is triboelectrically charged within said nozzle, and a turbulence generator arranged inside of said nozzle. The surface of said turbulence generator is coated with a plastic material possessing an electrification series remarkably different from that of said powdered paint.
