PROBLEM TO BE SOLVED: To provide a curvature correction mechanism in which the vibration of a reflecting mirror is suppressed, the bow of main scanning line is excellently corrected, the large dimensions, the reduction in margin of layout and increase in the cost of the apparatus are suppressed, and to provide an optical scanner, to provide an image forming apparatus and a method of manufacturing the optical scanner.SOLUTION: In the original state immediately after an apparatus is assembled, a predetermined gap is formed between the lower face of a reflection mirror 45Y and a double-sided tape 120Y. In this state, the bow of main scanning line on a photoreceptor is adjusted as is described in the foregoing section. After the bow of the main scanning line is adjusted, the upper face of the reflecting mirror 45Y is depressed downward by using a stick-shaped tool from a cutout part 52cY of a holder 52Y, the lower face of the reflection mirror 45Y is brought into press contact with the double-sided tape 120Y, the lower face of the reflecting mirror 45Y is fixed on the lower face of the holder 52Y with the double-sided tape 120Y. |
