PROBLEM TO BE SOLVED: To provide an actuator, an optical scanner, and an image forming apparatus capable of reducing a distance between a coil and magnets to achieve efficient drive of a movable part.SOLUTION: An optical scanner 1 includes a movable part 21 that can be swung around a swinging shaft, first connection parts 23 and 24 that extend from the movable part 21, a frame body part 22 that supports the first connection parts 23 and 24, second connection parts 25 and 26 that extend from the frame body part 22, and support parts 27 and 28 that support the second connection parts 25 and 26. The frame body part 22 is formed by surrounding the movable part 21, the first connection parts 23 and 24, the second connection parts 25 and 26, and the support parts 27 and 28. The optical scanner 1 further includes a coil 51 provided to the frame body part 22, and permanent magnets 52 and 53 that generate a magnetic field acting on the coil 51. |
