PURPOSE: An ink injector of an ink jet printer is provided to simplify structure, to reduce a consumption amount of ink and to readily change the size of a nozzle injection hole and the design of a position. CONSTITUTION: An ink injector of an ink jet printer comprises power; a nozzle beam having a lever on both sides and forming a closed circuit by being connected to a bridge; magnets(12,13) installed on upper and lower parts of the nozzle beam to feed a magnetic field; and a nozzle plate(17) prepared with plural nozzle orifices formed on a front face of the nozzle beam. When a current is supplied to a conductive beam(11), the attraction of levers(11b,11'a,11'b,11"a) of the conductive beams(11,11',11") is reacted by different current flows. As the levers are bent toward an ink chamber containing ink, a space of the ink chamber(16) is compressed. The ink is injected through the plural nozzle orifices(11c,11'c,11"c) formed on the nozzle plate so that a print work is performed.
