PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus, or a liquid jet apparatus in a broad category, which can realize recording with high precision. SOLUTION: A head member with a nozzle opening is moved in such a manner as to pass through a plurality of passage positions. The pressure of a liquid in a nozzle opening part fluctuates on the basis of a driving pulse which is generated from an ejection driving signal, so that a liquid droplet can be ejected from the nozzle opening. The ejection driving signal comprises a first pulse waveform signal PW1 for ejecting an ink droplet after a lapse of first pulse standby time from each of a plurality of timings specified in such a manner as to correspond to the plurality of passage positions, and a second pulse waveform signal PW2 for ejecting the ink droplet after a lapse of second pulse standby time. The pulse standby times are each specified in terms of each of the timings, on the basis of the moving speed of the head member, and the ejection speed of the liquid droplet to be ejected.
