ABSTRACT:
There is disclosed an ink-droplet ejecting apparatus including a pressure chamber filled with an ink, an actuator which varies an inner volume of the pressure chamber, and a control unit which has a drive-signal generator. The drive-signal generator generates a drive signal and applies the drive signal to the actuator when a droplet of the ink is to be ejected onto a recording medium The drive signal is generated to be in one of at least one waveform including a waveform including a main pulse Pm in order to eject the ink droplet, and a stabilizing pulse Ps applied after the main pulse Pm in order not to eject an ink droplet. A pulse width Ts of the stabilizing pulse Ps is smaller than a rising time of the stabilizing pulse Ps.
