ABSTRACT:
A multi-beam scanning device includes a light source part having a plurality of light emitting sources which light emitting sources are monolithically arranged in a surface perpendicular to an optical axis; a light deflection part configured to deflect a plurality of light beams from the light source part in a lump and scan an image carrier surface; and an image-formation optical system where lateral magnification is set so that beam spots of the plural light beams are arranged at a designated pitch in a sub-scanning direction on the image carrier surface.
