1. An optical scanner comprising:
- a light reflecting section having light reflectivity;
a movable section which includes the light reflecting section and can be displaced;
two link sections connected to positions of ends of the movable section, the positions facing each other;
a supporting section supporting the link sections; and
a displacement providing section turning the two link sections,wherein each link section includes;
a turnable drive section, anda shaft section connecting the movable section and the turnable drive section and bending in a thickness direction of the movable section by turning of the turnable drive section; and
wherein when two axes which are at right angles to one another in a plan view of the movable section are an X axis and a Y axis,each of the two link sections has the turnable drive section placed so as to be away from the movable section in an X-axis direction, a first shaft section which is the shaft section connecting the movable section and the turnable drive section and extending in the X-axis direction, and a second shaft section connecting the turnable drive section and the supporting section and extending in a Y-axis direction, andthe first shaft section is bent by making the displacement providing section turn the turnable drive section about the Y axis while torsionally deforming the second shaft section.

15. An optical scanner comprising:
-
a movable section including a light reflecting section having light reflectivity; a supporting section supporting the movable section; two link sections provided on both sides of the movable section and connecting the movable section and the supporting section; and a displacement providing section displacing the movable section, wherein each link section has a drive section which is turnable with respect to the supporting section and a shaft section connecting the drive section and the movable section, the shaft section of each link section can bend in a thickness direction of the movable section in a midpoint of the shaft section in a longitudinal direction, and the movable section is displaced by making the displacement providing section turn the drive section of each link section and bend the shaft section by the turning, when two axes which are at right angles to one another in a plan view of the movable section are an X axis and a Y axis, each of the two link sections has the drive section placed so as to be away from the movable section in an X-axis direction, a first shaft section which is the shaft section connecting the movable section and the drive section and extending in the X-axis direction, and a second shaft section connecting the drive section and the supporting section and extending in a Y-axis direction, and the first shaft section is bent by making the displacement providing section turn the drive section about the Y axis while torsionally deforming the second shaft section.

16. An image forming apparatus, comprising:
-
a light source; and an optical scanner scanning a light from the light source, wherein the optical scanner includes a light reflecting section having light reflectivity, a movable section which includes the light reflecting section and can be displaced, two link sections connected to positions of ends of the movable section, the positions facing each other; a supporting section supporting the link sections; and a displacement providing section turning the two link sections, and each link section includes; a turnable drive section, and a shaft section connecting the movable section and the turnable drive section and bending in a thickness direction of the movable section by turning of the turnable drive section, wherein when two axes which are at right angles to one another in a plan view of the movable section are an X axis and a Y axis, each of the two link sections has the turnable drive section placed so as to be away from the movable section in an X-axis direction, a first shaft section which is the shaft section connecting the movable section and the turnable drive section and extending in the X-axis direction, and a second shaft section connecting the turnable drive section and the supporting section and extending in a Y-axis direction, and the first shaft section is bent by making the displacement providing section turn the turnable drive section about the Y axis while torsionally deforming the second shaft section.
