Abstract
The drive control device of a light scanning apparatus can be easily controlled, occurrence of overshoot can be prevented, and a scanning range of a mirror section can be adjusted in a short time. An amplitude adjusting section generates at least one of first adjusting voltage for acceleration, whose amplitude is higher than that of adjusting voltage for obtaining object amplitude, and second adjusting voltage for deceleration, whose amplitude is lower than that of the adjusting voltage for obtaining the object amplitude, and applies the same to a drive circuit for a prescribed time, to perform feedback control, when a comparing section generates an error signal, so as to cancel increase-decrease variation of the error signal.
