ABSTRACT:
An optical beam scanning device of the present invention has a light source, a deflection reflecting surface for deflecting to scan light from the light source on a recording medium, and a diaphragm device which is provided between the light source and the deflection reflecting surface, and the diaphragm has an opening section formed by a nonplanar light shielding section. The light shielding section makes light shielding quantity of the light from the light source in a vertical scanning direction different in positions in a horizontal scanning direction and in a light advancing direction.
