An optical writer includes a housing, a light source, a deflector, and a plurality of optical elements. The housing includes a plurality of surfaces, one of which includes a substantially flat portion having an opening formed therein and a curved portion curved in the shape of an arc of a circle in cross-section. The light source is enclosed within the housing and projects light through the opening and onto a target. The deflector is enclosed within the housing and deflects the light projected from the light source in a main scanning direction. The plurality of optical elements is enclosed within the housing and directs the light deflected by the deflector onto the target.
