Claim 3:
4. The droplet discharging apparatus according to claim 3, wherein:
each of the first driving waveform and the second driving waveform has a rising portion, a falling portion, and an intermediate portion between the rising portion and the falling portion;
each of the rising portions of the first driving waveform and the second driving waveform appears between a first point of time and a second point of time;
each of the intermediate portions of the first driving waveform and the second driving waveform appears between a second point of time and a third point of time;
each of the falling portions of the first driving waveform and the second driving waveform appears between a third point of time and a fourth point of time;
the second point of time is later than the first point of time, the third point of time is later than the second point of time, and the fourth point of time is later than the third point of time;
each of the third driving waveform and the fourth driving waveform has a rising portion, a falling portion, and an intermediate portion between the rising portion and the falling portion;
each of the rising portions of the third driving waveform and the fourth driving waveform appears between a fifth point of time and a sixth point of time;
each of the intermediate portions of the third driving waveform and the fourth driving waveform appears between a sixth point of time and a seventh point of time;
each of the falling portions of the third driving waveform and the fourth driving waveform appears between a seventh point of time and an eighth point of time;
the sixth point of time is later than the fifth point of time, the seventh point of time is later than the sixth point of time, and the eighth point of time is later than the seventh point of time; and
a length between the first point of time and the second point of time is different from a length between the fifth point of time and the sixth point of time, a length between the second point of time and the third point of time is different from a length between the sixth point of time and the seventh point of time, or a length between the third point of time and the fourth point of time is different from a length between the seventh point of time and the eighth point of time.
