Abstract:
1. An optical scanning apparatus comprising: a light source configured to emit a light beam; a deflecting unit configured to deflect the light beam from the light source such that the light beam scans a photosensitive member; an optical lens configured to guide the light beam deflected by the deflecting unit onto the photosensitive member; a lens supporting unit having a fixing portion to which a first end of the optical lends in a longitudinal direction thereof is fixed, and a movable supporting portion to which a second end of the optical lens in the longitudinal direction thereof is fixed by adhesive, wherein the movable supporting portion is attached to the lens supporting unit such that a movement of the movable supporting portion is restricted in a direction perpendicular to both of the longitudinal direction of the optical lens and an optical axis direction of the optical lens, the movement of the movable supporting portion is restricted in the optical lens, the movement of the movable supporting portion is restricted in the optical axis direction of the optical lens, and the movable supporting portion moves in the longitudinal direction of the optical lens by movement of the second end of the optical lens fixed in the longitudinal direction of the optical lens.
