PROBLEM TO BE SOLVED: To provide an ink-jet recording device capable of preventing distortion of a driving waveform substantially completely in a simple configuration, eliminating the influence by irregularity of the ON resistance of an analog switch, or the like, and applying an accurate waveform highly stably to each pressure generating element. SOLUTION: By providing a dummy piezoelectric vibrator 17' and always having an analog switch 160' ON, the piezoelectric vibrator 17' is always driven as well as the terminal voltage of the dummy piezoelectric vibrator 17 is returned (feed back) to an operation amplifier 86'. By having the returning (feedback) operation by the voltage applied on the piezoelectric vibrator 17', a highly accurate driving waveform with little distortion can be provided to a plurality of piezoelectric vibrators.
