Actuator and light scanning apparatus

A method for driving an object to be driven using an actuator including

• a beam configured to support the object to be driven, and a drive source, the method comprising:
• generating a first staircase waveform that is oscillation of a ringing suppressing waveform for suppressing a ringing waveform to be generated;
• generating a second staircase waveform that causes the ringing waveform to occur, the second staircase waveform continuing from the first staircase waveform;
• generating a drive signal, the drive signal combining the first staircase waveform and the second waveform so as to have a shape of sawtooth waveform in a rising of a drive waveform;
• and
• driving the object to be driven with the drive source so as to swing in a direction of rotating around a predetermined axis while suppressing the ringing waveform.
