A resonance pulse is a voltage waveform substantially containing an expansion element for varying a voltage to expand a pressure chamber, an expansion sustaining element generated following with the expansion element, and sustaining a maximum voltage at a predetermined value, and a contraction element generated following with the expansion sustaining element, and varying the voltage to contract the pressure chamber. A time span from a front end of the expansion element to a front end of the contraction element is set as ½ of an inherent vibration cycle of ink in the pressure chamber. |
