PROBLEM TO BE SOLVED: To provide an inkjet recorder capable of delivering stably three drops or more of mutlidrops while restraining a shooting position from being deviated, without complicating a drive circuit. SOLUTION: In this inkjet recorder, a waiting time of the first pulse applied at first is longer than two times of an AL (AL represents 1/2 of acoustic resonance frequency of a pressure chamber) and shorter than four times thereof, out of at least three driving pulses applied within one printing period, a waiting time of the last pulse applied at the last is even number times of the AL, a waiting time of each intermediate pulse applied between the first pulse and the last pulse is one time or more and less than two times of the AL, voltages of expansion pulses are substantially equal each other in the respective driving pulses, and voltages of contraction pulses are substantially equal each other.
