摘要：
According to one embodiment, an ink jet head includes pressure chambers filled with liquid, nozzles discharging the liquid that is in the pressure chambers, actuators changing the capacity of the pressure chambers, and a processor. The processor repeatedly outputs a waveform voltage including an expansion pulse, a ground potential, a contraction pulse, and a ground potential in this order, as a driving voltage with respect to the actuators.
