Abstract: A light scanning unit, a method of controlling, and an image forming apparatus having the same are provided. The light scanning unit includes: a light source; a beam deflector which reciprocally scans a light beam radiated from the light source to form an image range and a first non-image range and a second non-image range on opposite sides of the image range; a reflecting member which reflects a light beam deflected from the beam deflector to the first non-image range; and a sensor which senses the light beam deflected from the beam deflector to the second non-image range and the light beam reflected on the reflecting member.
