Abstract:
An optical scanning device deflects a light beam emitted from a light source device by a vibrating mirror, scans a scanning surface with deflected light beam, and focuses the light beam onto the scanning surface by a scanning imaging optical system. The optical scanning device includes an offset detecting unit that detects an offset that is a deviation between a center of vibration amplitude of the vibrating mirror and a center of an optical scanning area and an adjusting unit that adjusts the center of the vibration amplitude when the offset detected by the offset detecting unit is larger than a predetermined value.
