PURPOSE: An ink injector of an inkjet printer, the inkjet printer and an injection method thereof are provided to continuously inject ink by generating a flow inside liquid ink through discharging shock waves. CONSTITUTION: An ink injector of an inkjet printer comprises a nozzle(101), an ink chamber, plural electrodes(107,107') and a high voltage supply unit(102). The nozzle injects liquid ink. The ink chamber stores the liquid ink. The electrodes generate a discharging inside the ink chamber. The high voltage supply unit feeds the voltage for discharging to the electrodes. Thereby, the property change of the liquid ink by heat is reduced, many nozzles are installed in a narrow area by a simple structure of a head and the operating speed is increased by using a discharging principle.
