An inkjet head driving method is a method for driving an inkjet head having a property in which heat is generated when a drive waveform is applied to a piezoelectric element section connected to a plurality of discharge nozzles. Based on drawing data, a discharge waveform, which is a drive waveform that causes discharging of ink, is applied to a driven nozzle for discharging the ink in a predetermined drive cycle, and a non-discharge waveform, which is a drive waveform that does not cause discharging of the ink, is applied to a non-driven nozzle other than the driven nozzle in the predetermined drive cycle.
