Abstract: A piezoelectric element changes a pressure in a pressure chamber and ejects ink from nozzles. A driving signal generating section generates a driving signal that includes an ejection pulse PA and PB which eject ink to a piezoelectric element, and a first transition element between the ejection pulse PA and PB. A starting end and a terminal end of the ejection pulse PA are set to a reference electric potential VA, and a starting end and a terminal end of an ejection pulse PB are set to a reference electric potential VB. An electric potential difference between the reference electric potential VA and the lowest electric potential of the ejection pulse PA is smaller than an electric potential difference between the reference electric potential VB and a highest electric potential of the ejection pulse PB, and the reference electric potential VA is lower than the reference electric potential VB.
