Abstract:
Provided is a drive method of a liquid discharging head including a first step of forming a first liquid column by supplying a drive signal having a first waveform to a drive element, and a second step of, when the first liquid column is formed, forming a second liquid column by supplying a drive signal having a second waveform to the drive element, and thereafter discharging a part or all of liquid constituting the second liquid column as a droplet, in which when a drive signal having the first waveform but not having the second waveform is supplied to the drive element, a droplet is not discharged from the discharging portion, and when a drive signal having the second waveform but not having the first waveform is supplied to the drive element, a droplet is not discharged from the discharging portion.
