Abstract

A light scanning includes an adjusting unit that displaces the optical member to adjust the optical axis of the laser beam. The adjusting unit includes a shaft portion, a shaft supporting portion, a turning portion, a driving portion, and a turning damping unit. The shaft portion is configured to bidirectionally move in a first direction and in a second direction while turning. The first direction is a direction where the shaft portion approaches the optical member. The second direction is a direction where the shaft portion moves away from the optical member. The shaft supporting portion supports the shaft portion, and moves the shaft portion in accordance with turning of the shaft portion. The turning portion turns the shaft portion. The driving portion turns the turning portion. The turning damping unit damps a turning force applied to the shaft portion by an external force.
