PROBLEM TO BE SOLVED: To provide a liquid ejection device having stability in liquid ejection.SOLUTION: A liquid ejection device includes: an ejection head having a pressure chamber communicating with a nozzle and a pressure generating part for generating a pressure variation in a functioning liquid in a pressure chamber; and a control part that generates a driving signal including a micro vibration pulse to a degree where liquid droplets are ejected from the nozzle and drives the pressure generating part based on the driving signal. In the control part, the micro vibration pulse including a stirring vibration pulse for stirring the functional liquid and a heating vibration pulse for heating the functional liquid are generated. |
