In recording an image by an inkjet printer, when not forming a dot on a recording paper, non-ejection operation of droplet is performed in a head part by a non-ejection pulse (P21) which indicates the non-ejection operation and which is included in each driving signal, and when forming a medium dot, a droplet(s) is ejected from an outlet by the non-ejection pulse (P21) and an ejection pulse (P12) included in the driving signal. It is therefore possible to appropriately form dots having a desired size without adding any ejection pulse to the driving signal in high-speed image recording.
