PURPOSE:To obviate the necessity for a deflecting electrode so as to reduce the distance between a nozzle and a drum, thereby simplifying an electrode unit by forming two holes in a nozzle and providing an electrifying electrode for synchronizing ink particles injected through these two holes as well as electrifying the two ink particles so injected so as to allow them to be the same poles. CONSTITUTION:Two holes (orifices) are formed in a nozzle 10 at positions equally away from the center thereof in the same conditions. Ink particles pressurized by means of the nozzle 10 so as to be synchronized are deformed to be constricted by means of a piezo-vibrator and thereby become granular particles. A pulse voltage of about 500V is impressed to these granular particles from an electrification control circuit 20, and ink particles are thereby electrified with a negative electric charge by virtue of static induction. The ink particles are caused to undergo a phase control at their broken points by utilizing an electricity control circuit, and electric signals are caused to synchronize with ink particles, whereby every other particles are fed as a setting signal from an electrifying electrode 12. As a result of this, the two ink particles are caused to deflect by the action of interparticle repulsion so as to be set on an exclusive coated paper on a drum 16 after passing through a garter 14. |
