摘要： An optical scanning device includes a light source, a deflector, and an image-forming optical system. The deflector includes a deflecting surface for deflecting light beams in a main scanning direction. The image-forming optical system includes two relay lenses having a positive power in the main scanning direction. The relay lenses cause main light beams of light beams emitted from the light source to cross near the deflecting surface in the main scanning direction.

摘要： A two-dimensional array include N light-emitting arrays each formed of M light-emitting units arranged equally spaced along a direction T tilting from a main scanning direction at an angle α toward a sub-scanning direction. The light-emitting arrays are equally spaced in the sub-scanning direction. A space ds2 between light-emitting arrays with respect to the sub-scanning direction satisfies ds2=ds1×M where ds1 is a positional difference in the sub-scanning direction between light-emitting units which are adjacent each other in the main scanning direction and orthographically-projected on a virtual line extending in the sub-scanning direction. The angle α satisfies α=sin−1((ds2/d1)/M) where d1 is a space between light-emitting units in the light-emitting array with respect to the direction T. The space ds2 is equal to the space d1.

摘要： An optical scanning device includes a light source, a light-beam splitting unit, a deflector, and a scanning optical system. The light-beam splitting unit splits a light beam from the light source into a plurality of light beams, so that the light beams are each incident to any one of reflecting surfaces of the deflector while having a phase difference of approximately π/2. The scanning optical system receives the light beams from the deflector and projects each of the light beams onto a corresponding target surface.
