An image scanning method capable of obtaining an image with good image quality is provided. A light emitting actuator having a first driving unit and a second driving unit for driving an emitting end portion of an optical fiber in different directions displaces an emitting end portion in a two dimensional direction so that light emitted from the optical fiber is In scanning, the first drive signal to be supplied to the first drive section and the second drive signal to be supplied to the second drive section are controlled by the drive control section, so that the scanning locus of the light is kept substantially constant And rotated while reciprocating repeatedly with a length to scan a circular scanning area.画質の良好な画像が得られる光走査方法を提供する。 光ファイバの射出端部を異なる方向に駆動する第１の駆動部及び第２の駆動部を有する光走査用アクチュエータにより射出端部を２次元方向に変位させて、光ファイバから射出される光を走査するにあたり、第１の駆動部に供給する第１の駆動信号及び第２の駆動部に供給する第２の駆動信号を駆動制御部により制御して、光の走査軌跡をほぼ平行に一定の長さで繰り返し往復させながら回動させて、円形状の走査領域を走査する。
