Abstract

A liquid discharging device includes: a recording head that has nozzles discharging liquid, and forms an image on a target surface with the liquid while performing scanning of the target surface for multiple times; a moving unit that moves the recording head in main-scanning direction while making the head discharge liquid, and moves the head in sub-scanning direction after the head has discharged liquid; a drive waveform applying unit that applies a drive waveform to the respective nozzles; a temperature detecting unit that detects temperature about the head; a correcting unit that corrects drive waveform based on detected temperature; and a control unit that, when temperature about the head changes from first temperature to second temperature, performs control in such a way that, during the multiple scans, use of second-type drive waveform corresponding to the second temperature gradually increases against use of first-type drive waveform corresponding to the first temperature.
