Abstract
An optical scanner having a light source for emitting a light beam, an optical deflector having a deflecting-reflecting face for deflecting the light beam at a constant angular speed and a scan image forming mirror for reflecting the deflected light beam to a surface to be scanned at a constant speed. The light source and the optical deflector are provided on opposite sides across the scan image forming mirror and the light beam is illuminated toward the deflecting-reflecting face of the optical deflector through an emitted-light transmitting portion provided outside an effective area of the scan image forming mirror.
