Abstract
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.
