| description | PROBLEM TO BE SOLVED: To provide an optical scanner capable of stably rotating movable plates about two axes orthogonal to each other, respectively, and an image forming apparatus.SOLUTION: A permanent magnet 811 inserted into a through-hole 411 is fixed to alignment surfaces 41X and 41Y to be fixed by being positioned at a desired position of a displacement part 41, for details, a center of a X-axis direction dimension and a center of a Y-axis direction dimension of the permanent magnet 811 can be made to coincide with an intersection of rotary center shafts X1 and X2. Accordingly, when alternate voltage is applied to coils 812 and 832 from power sources 813 and 833, the permanent magnet 811 is inclined, and the displacement part 41 is stably inclined around the rotary center shaft Y2, while twisting and deforming a driving beam 43, without shifting from the rotary center shaft Y2. A movable beam 42 therefore is capable of stably rotating a movable part 2 without bending shifted and inclined from the rotary center shaft X1. |
