摘要： An optical scanner includes a light source, optical deflector, mirror, first photosensitive drum, and second photosensitive drum. The light source emits a first light beam and a second light beam. The optical deflector deflects the first light beam and the second light beam. The mirror has a reflecting part that reflects the deflected first light beam and a passing part that passes the deflected second light beam. The passing part is displaced from the reflecting part. The first photosensitive drum performs a development with a first toner having a first color. The reflected first light beam scans the first photosensitive drum in a main scanning direction. The second photosensitive drum performs a development with a second toner having a second color different from the first color. The passed second light beam scans the second photosensitive drum in the main scanning direction. The first photosensitive drum and second photosensitive drum are arranged in a sub scanning direction orthogonal to the main scanning direction.

摘要： 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.
