Abstract
A light scanning device includes: a first semiconductor laserthat emits a light beam L; a polygonal mirrorthat deflects the light beam L; a reflective mirrorthat reflects the light beam Ldeflected by the polygonal mirrorand causes the light beam Lto enter a photosensitive drum; and a BD sensorthat detects the light beam Ldeflected by the polygonal mirror. The light scanning device scans the photosensitive drumwith the light beam Land set scanning timing of the photosensitive drumusing the light beam Lbased on detection timing of the light beam Lusing the BD sensor. The BD sensoris arranged in the position farther from the polygonal mirrorthan the last reflective mirrorthat reflects the light beam Limmediately before entering the photosensitive drumand arranged inside a scanning angle range α of the light beam Lcorresponding to an effective scan area of the photosensitive drum
