Zusammenfassung:	To provide an optical scanning device capable of stably drawing an image, and also to provide a method of driving the optical scanning device, and an image drawing system.SOLUTION: A drive control part performs the steps of: applying a first drive signal having a first drive frequency to a first actuator which swings a mirror part around a first axis; applying a second drive signal having a second drive frequency to a second actuator which swings the mirror part around a second axis intersecting with the first axis; and deriving a first drive condition of the first actuator whose first drive frequency is less than a first resonance frequency around the first axis.SELECTED DRAWING: Figure 8 【課題】安定して画像を描画することができる光走査装置、光走査装置の駆動方法、及び画像描画システムを得る。【解決手段】駆動制御部は、第１軸の周りにミラー部を揺動させる第１アクチュエータに第１駆動周波数を有する第１駆動信号を付与し、第１軸に交差する第２軸の周りにミラー部を揺動させる第２アクチュエータに第２駆動周波数を有する第２駆動信号を付与し、第１駆動周波数が第１軸周りの第１共振周波数未満となる第１アクチュエータの第１駆動条件を導出する。【選択図】図８
