Abstract
A light scanning apparatus includes a deflector for deflecting a light beam emitted from a laser. A rotating reflector is provided in the deflector, and a reflecting surface is formed on the rotating reflector by cutting away a portion of the rotating reflector diagonally with respect to a plane perpendicular to the axis thereof. The light scanning apparatus further includes a control device for controlling a stopping position of the rotating reflector such that the rotating reflector stops rotating in a state in which the reflecting surface faces a predetermined direction. A magnet, an electromagnet, or a gear mechanism may be used as the control device.
