PROBLEM TO BE SOLVED: To provide an optical scanner, with which various characteristics are measured as a single unit of the optical scanner, the position of such an optical component as a scanner motor is easily adjusted and the vibration of the optical components and the optical scanner as a whole is suppressed. SOLUTION: The optical scanner has a rigidity-enhancing member 30, which is connected to a housing 20 that holds optical components 1 and 2 and enhances the rigidity of a connected body C, in which the member and the housing 20 are connected to a value larger than the rigidity of the housing itself, and the optical scanner is made detachable from an image forming apparatus F. The optical scanner 10 is fixed to the image forming apparatus, by fixing the rigidity enhancing member 30 to the fixing portion F of the optical scanner 10 in the image forming apparatus.
