Abstract:
1. A liquid ejecting device comprising: a channel member formed with liquid channels having ejection ports for ejecting droplets, the channel member having a surface formed with a plurality of openings through which a part of each liquid channel is exposed; an actuator including a layered body disposed on the surface of the channel member so as to confront the plurality of openings for applying energy to liquid in the plurality of openings, the layered body including a first piezoelectric layer and a second piezoelectric layer stacked from a side closer to the plurality of openings in this order, each of the first and second piezoelectric layers being sandwiched between electrodes with respect to a stacking direction; a driving-signal generating section configured to generate driving signals for driving the actuator, the driving-signal generating section being configured to generate an ejection driving signal for ejecting droplets from the ejection ports and a non-ejection driving signal for vibrating a meniscus formed in the ejection ports without ejecting droplets from the ejection ports; and a voltage applying section configured, based on image data of an image to be recorded on a recording medium, to apply a voltage corresponding to the ejection driving signal to electrodes sandwiching one of the first and second piezoelectric layers during a first period, and to apply a voltage corresponding to the non-ejection driving signal to only electrodes sandwiching an other one of the first and second piezoelectric layers during a second period different from the first period.
