    • An optical scanner includes a light source, a polygon mirror, an optical member, a casing, and an exit hole cover. The light source emits a light beam. The polygon mirror rotates and deflects the light beam to be scanned in a scanning direction. The optical member focuses the light beam deflected by the polygon mirror onto a scanning target. The casing houses the polygon mirror and the optical member and includes a first wall portion having a wall inner surface opposing the polygon mirror and the optical member and a wall outer surface opposing the scanning target. The first wall portion is formed with an exit hole through which the light beam is irradiated toward the scanning target. The exit hole cover is formed of a light transmissible member and is disposed on the wall outer surface to cover the exit hole.
