<P>PROBLEM TO BE SOLVED: To provide an inkjet recorder which comparatively simplifies a head structure, densifies it, and reduces a number of its physical mechanisms so that a printing speed increases and pixels highly densifies, and easily carried out full colorization. Ž<P>SOLUTION: In the inkjet recorder which performs recording by making a droplet fly from an ink surface by a convergent ultrasonic wave, a bubble 21 for an ultrasonic wave shutter is provided on the way to propagate the convergent ultrasonic wave. The transmission of the ultrasonic wave to the liquid surface is selectively shut off by timely opening or closing the bubble 21, in order to control the droplet flying from the liquid surface.
