ABSTRACT:
In an ink jet head driving method for applying a drive pulse to an actuator ACT to change capacities of a plurality of pressure chambers in which ink has been filled, ejecting an ink droplet from a nozzle formed in communication with the pressure chamber to print onto a printing medium, and moreover, controlling the number of ink droplets ejected according to the number of drive pulses to carry out gradation printing, a control is made such that, in the case where the number of ink droplets is small, a boost pulse Pb for amplifying a pressure vibration of the pressure chamber is applied prior to a drive pulse for ejecting a first ink droplet, and in the case where the number of ink droplets is large, applying of the boost pulse Pb is disabled.
