    摘要: PROBLEM TO BE SOLVED: To provide a method of driving an inkjet recording head wherein controlling of vibration is carried out, residual vibration is suppressed, an ink droplet is stably ejected by maintaining the ejection speed of the ink droplet and the volume of the ink droplet in an adequate level, thereby preventing quality of an image from being lowered, and to provide an inkjet recorder.
    SOLUTION: In this method of driving the inkjet recording head, variation in a pressure is generated in a pressure generating chamber filled with ink by a pressure generating element and an ink droplet is ejected from a nozzle communicating with the pressure generating chamber. The method includes at least a first signal A for ejecting the ink droplet by contracting the pressure generating chamber, a second signal B for maintaining the contracting condition of the pressure generating chamber and a third signal C for suppressing residual vibration of a meniscus after the ejection of the ink droplet by contracting or expanding the pressure generating chamber.
