Abstract
An ink jet recording apparatus includes: a head body provided with a nozzle and a pressure chamber; an actuator including a piezoelectric element and an electrode for applying a voltage across the piezoelectric element; and a driving circuit for supplying a driving signal to the electrode of the actuator. The driving signal includes, in one printing cycle, a pulse signal applied with an interval that is shorter than a predetermined pulse interval being equal to a Helmholtz period of a head, and a pulse signal applied with an interval that is longer than the predetermined pulse interval.
