Liquid ejection head and liquid ejection device

A liquid ejection device comprising:

• a liquid ejection head for ejecting liquid onto a medium;
• and
• a controller configured to control the liquid ejection head, wherein
• the liquid ejection head includes:
• a nozzle plate having a nozzle through which liquid is ejected,
• a pressure chamber communicating with the nozzle,
• an actuator configured to change a volume of the pressure chamber in response to a drive signal, and
• a drive circuit configured to generate the drive signal, wherein
• the drive signal includes a plurality of ejection waveforms for causing the nozzle to eject a plurality of droplets, and a suppression waveform that is input between the plurality of ejection waveforms and suppresses residual vibration generated by a preceding ejection waveform,
• an ejection waveform that is input immediately after the suppression waveform is input at a timing at which vibration generated by the ejection waveform and vibration generated by the suppression waveform intensify each other, and
• a speed of a droplet ejected by the ejection waveform that is input immediately after the suppression waveform is greater than a speed of a droplet ejected by an ejection waveform that is input prior to the suppression waveform.
