The driving signal includes an ejection driving pulse that ejects a liquid droplet and a non-ejection driving pulse that drives the pressurizing element to a degree whereby a liquid droplet is not ejected. The ejection driving pulse is a pulse waveform having an expansion element that causes the pressurizing chamber to expand and retract a meniscus toward the pressurizing chamber and a constriction element that causes the pressurizing chamber expanded by the expansion element to constrict and push the meniscus in the direction of ejection. The non-ejection driving pulse is a pulse waveform having an expansion element that causes the pressurizing chamber to expand and retract the meniscus toward the pressurizing chamber, a holding element that holds the voltage at the end of the expansion element for a set amount of time, and a constriction element that causes the pressurizing chamber expanded by the expansion element to constrict and push the meniscus in the direction of ejection. When the length of time from the end of the constriction element in the ejection driving pulse to the beginning of the expansion element in the non-ejection driving pulse is taken as t, the lengths of time of the expansion element, holding element, and constriction element in the non-ejection driving pulse are taken as a, b, and c, respectively, and the inherent vibration cycle of the liquid within the pressurizing chamber is taken as Tc, t, a, b, and c are within the ranges defined by the following equations (1) through (3): | 09-30-2010 |
