Claim 15:
16. The drive waveform determination method according to claim 1, wherein
the first drive pulse includes a first state in which a first reference potential changes to a first potential lower than the first reference potential, a second state in which after the first state, the first potential changes to a second potential higher than the first reference potential, and a third state in which after the second state, the second potential changes to the first reference potential, and
the second drive pulse includes a fourth state in which a second reference potential changes to a third potential lower than the second reference potential, a fifth state in which after the fourth state, the third potential changes to a fourth potential higher than the second reference potential, and a sixth state in which after the fifth state, the fourth potential changes to the second reference potential.
