Abstract

A light scanning device (15) includes a light source (32), a deflector (33), a reflection mirror (43), and a light width regulating portion (44). The light source (32) includes a plurality of light-emitting elements (32a, 32b, 32c, 32d) located at intervals one another. The deflector (33) deflects to scan by reflecting a plurality of light beams. The plurality of light beams are emitted from the respective light-emitting elements (32a, 32b, 32c, 32d). The reflection mirror (43) is located in an optical path between the light source (32) and the deflector (33) and guides the plurality of light beams emitted from the plurality of light-emitting elements (32a, 32b, 32c, 32d) to the deflector (33). The light width regulating portion (44) regulates widths of the plurality of light beams reflected by the reflection mirror (43) in a main-scanning direction. The light width regulating portion (44) is located adjacent to a reflecting surface of the reflection mirror (43) and includes a pair of regulating wall portions (44) located opposed one another in the main-scanning direction.
