PROBLEM TO BE SOLVED: To provide a liquid ejecting apparatus that can obtain a superior liquid ejection quality by decreasing satellites and a driving method thereof.SOLUTION: A voltage of waveforms including an expansion pulse, ground potential, and a contraction pulse sequentially is output as a drive voltage to eject one droplet from a nozzle. Then, the period of the expansion pulse is set to a half value of the resonance period of the liquid and a pressure chamber, the period of the ground potential is set to the period that combines the calibration period of the necessary minimum and the adjustment period, and the period of the contraction pulse is set to the period that decreases the adjustment period from the resonance period. |
