Abstract
An ink jet recording apparatus includes an ink jet head having a nozzle, an ink channel, a diaphragm, and an electrode and a part applying first and second driving signals to the ink jet head. The first driving signal generates electrostatic force that deforms the diaphragm so as to eject an ink droplet from the nozzle. The second driving signal for controlling deformation of the diaphragm is applied after a predetermined period of time passes since application of the first driving signal.
