Patent ID: 8256864

Claim:
A liquid ejecting apparatus comprising: a liquid ejecting head that applies a variation in the pressure to the inside of a pressure chamber by operating a pressure generating unit and ejects a liquid filled in the pressure chamber from a nozzle; and a driving signal generating unit that is capable of generating a driving signal containing an ejection driving pulse for ejecting the liquid from the nozzle to a landing target by driving the pressure generating unit, wherein the ejection driving pulse is a voltage waveform including: a first changing portion that changes a potential from a middle potential in a first direction so as to change a volume of the pressure chamber; a first holding portion that holds a terminal potential of the first changing portion so as to hold the volume of the pressure chamber for a predetermined time; a second changing portion that changes the potential in a second direction opposite to the first direction so as to change the volume of the pressure chamber subjected to the first changing portion; a second holding portion that holds a terminal potential of the second changing portion so as to hold the volume of the pressure chamber for a predetermined time; and a third changing portion that returns the potential to the middle potential in the first direction so as to change the volume of the pressure chamber subjected to the second changing portion, wherein a time interval of the first changing portion is longer than that of the first holding portion, wherein a time interval of the third changing portion is longer than that of the second holding portion, wherein the middle potential is set to be 50% or more of the potential of the second holding portion, and wherein when the ejection driving pulse is applied to the pressure generating unit, a flow rate of the liquid ejected from the nozzle is 0.36 mg/s or more.
