Abstract
There is provided a controller which sets electrodes which are respectively disposed on wall surfaces of a plurality of ink chambers which are arranged in parallel so as to be separated from each other by partitions made of a piezoelectric material, to a high impedance state. In addition, at a timing when an identical potential is applied to the electrodes of at least three ink chambers which are arranged in parallel so as to be separated from each other by mutually adjacent partitions, the controller sets electrodes of ink chambers other than ink chambers located on both sides to a high impedance state.
