Abstract
Optical scanner for scanning a target surface with a light beam includes: a light deflector deflecting the light beam; a scanning lens made of resin and condensing the light beam deflected by the light deflector onto the target surface to form an image thereon; a frame to which the scanning lens is fixed and having a coefficient of linear expansion smaller than that of the scanning lens. The scanning lens is fixed to the frame at a first attachment portion and at least one second attachment portion of the scanning lens using adhesives. The first attachment portion is located closer to a center portion of a scanning range in a main scanning direction of the scanning lens than the second attachment portion is. A first adhesive used for the first attachment portion has an elastic coefficient greater than that of a second adhesive used for the second attachment portion.
