When a length of a central axis direction of a straight part is L [µm], and a floating speed of a bubble set according to a diameter d of a nozzle, a density Á of ink, and the diameter r of the bubble is Vr [µm/s], a flushing process is performed by driving an actuator with a flushing pulse within (L+5)/Vr [s] after a nozzle surface is wiped with a wiper so as to perform an ejecting operation. The flushing pulse in the flushing process is preferably a driving waveform which does not actively draw a meniscus in the nozzle toward a pressure chamber side from the initial position, and makes the ink be ejected from the nozzle by extruding the meniscus toward an ejecting side. |
