PROBLEM TO BE SOLVED: To provide an optical scanner driving circuit capable of performing highly accurate vibration control by eliminating the oscillation of the center of the vibration of the optical scanner. SOLUTION: This optical scanner driving circuit has a vibration driving means angularly vibrating a movable plate by supplying a current including an AC component to a driving coil, a vibration detecting means which is provided with a electromotive force detecting means detecting induced electromotive force generated in a sensor coil, a vibration frequency control means 401 controlling the frequency of the angular vibration, first vibration amplitude control means 403, 404, 405, 406, 407, 402, 412 controlling the amplitude of the angular vibration based on the detected signal to be outputted by the vibration detecting means and second vibration amplitude control means 403, 410, 411, 412 controlling vibration states having frequency components other then the angular vibration based on the detected signal to be outputted by the vibration detecting means.
