    • According to one embodiment, an inkjet head has a pressure chamber for storing an ink, an actuator for changing the volume of the pressure chamber, and a nozzle through which the ink stored in the pressure chamber is ejected when the volume of the pressure chamber is changed. Additionally, the inkjet head has a temperature sensor for detecting the temperature of the ink and a controller for controlling the actuator by outputting an ejecting waveform. The ejecting waveform sequentially includes an expansion pulse, a first contraction pulse, and a second contraction pulse. The controller changes the pulse width or voltage value of the second contraction pulse when the temperature detected by the temperature sensor changes.
