Abstract
An inkjet head includes a pressure chamber in which ink is stored, a nozzle plate including a nozzle which connects with the pressure chamber, an actuator configured to change a volume of the pressure chamber, and a drive circuit. The drive circuit, before a printing is performed, outputs, to the actuator for a first time period, a first signal for changing the volume of the pressure chamber without ejecting ink from the nozzle. A second signal for changing the volume of the pressure chamber is then output to the actuator for a second time period such that ink is ejected from the nozzle. A third signal for changing the volume of the pressure chamber to the extent that the ink is not ejected from the nozzle is then output to the actuator for a third time period.
