PROBLEM TO BE SOLVED: To provide an optical scanning device which reduces vibration of an image-forming lens.SOLUTION: The optical scanning device comprises: an image-forming lens 11 that guides a laser beam exposing a photoreceptor drum 2 to the photoreceptor drum; a support member 12 that has a stepping motor 16 at an end thereof for rotating the image-forming lens for correcting a direction of a laser beam scanning on the photoreceptor drum, and supports the stepping motor to allow the image-forming lens to be rotated; a vibration-absorbing member unit 32 that is connected to a protrusion section 25 of the support member, and reduces vibrations in the image-forming lens and the support member; and a housing body 21 that includes U-shaped groove 21a to which a shaft support member 14 being a convex part of the support member is fit and U-shaped groove 21c to which the vibration-absorbing member unit is fit. The image-forming lens and the support member are movable in the U-shaped groove 21a for adjusting an incident position of the laser beam relative to the image-forming lens. As to the vibration-absorbing member unit, a position is adjusted in the U-shaped groove 21c in response to the position adjustment of the image-forming lens and the support member. |
