Claim Text:
1. A light scanning device, comprising: a light-emitting element; a deflecting section configured to deflect a light beam emitted from the light-emitting element; at least one reflective mirror configured to reflect the light beam and cause the light beam to enter a scan object, the light beam being emitted from the light-emitting element and deflected by the deflecting section; and an optical sensor configured to detect the light beam deflected by the deflecting section, wherein the light scanning device is configured to scan the scan object with the light beam and set scanning timing of the scan object using the light beam based on detection timing of the light beam using the optical sensor, and the optical sensor is arranged in a position farther from the deflecting section than a last reflective mirror that reflects the light beam immediately before entering the scan object and arranged inside a scanning angle range of the light beam corresponding to an effective scan area of the scan object.
