description An optical deflector driving method includes inputting an instruction to change at least one of a first driving signal corresponding to a first driving voltage and a second driving signal corresponding to a second driving voltage, the first driving voltage and the second driving voltage being applied to an actuator swinging a mirror portion of an optical deflector around a swing axis; determining, in a case where the instruction is input, a timing when a voltage of a driving signal to be changed out of the first driving signal and the second driving signal becomes minimum; and reflecting, in a case where it is determined that the timing when the voltage of the driving signal to be changed becomes minimum comes, the change on the driving signal to be changed.
