PROBLEM TO BE SOLVED: To provide an optical scanner that can improve the quality of an image to be formed.SOLUTION: An optical scanner comprises: a light source 100 that emits light; a light separation part 203 that separates the light from the light source 100 into scanning light 101 for scanning an image forming part 206 and control light 102 for creating a signal that controls the state of scanning of the scanning light 101 and makes a direction of travel of the scanning light and a direction of travel of the control light different from each other; a light deflector 201 that swings a reflection surface and scans the image forming part 206 with the scanning light 101; a light receiving element 205 that receives the control light 102 and creates a signal; and a control part that controls the state of scanning of the light deflector 201 on the basis of the signal.SELECTED DRAWING: Figure 8
【課題】形成される画像の品質を向上することができる光走査装置を提供する。【解決手段】光を発する光源100と、光源100からの光を、画像形成部206を走査する走査光101と、走査光101の走査状態を制御する信号を生成するための制御光102とに分離し、走査光の進行方向と制御光の進行方向を異ならせる光分離部203と、反射面を揺動して画像形成部206を走査光101により光走査する光偏向器201と、制御光102を受光して信号を生成する受光素子205と、信号に基づいて光偏向器201の走査状態を制御する制御部と、を有する。【選択図】図8
