摘要： An optical scanning apparatus includes a deflector for deflecting a beam emitted from a light source, and scanning optical system having at least one scanning lens for causing the beam deflected by the deflector means to be imaged on a surface to be scanned. At least one scanning lens constituting the scanning optical system has a plurality of positioning reference surfaces for effecting the positioning of the scanning lens in the direction of the optical axis thereof, and is disposed so that a straight line linking the points on two positioning reference surfaces together or a plane formed by the points on three or more positioning reference surfaces may be non-orthogonal to the optical axis. In a main scanning cross-section, the shape of the effective portion of the scanning lens is asymmetrical with respect to the optical axis.

摘要： A multibeam scanning apparatus having a light source with multiple light emitting sections arranged at intervals in the sub-scanning direction, a light deflector for deflecting light beams emitted from the light emitting sections, and a photosensitive drum to be scanned in the main-scanning direction by the deflected light beams. The deflected light beams strike the photosensitive drum with an angle of inclination relative to the normal of the surface of the photosensitive drum as viewed in the sub-scanning direction in order to scan the drum at predetermined intervals. The intervals between the light beams are selected to be smaller than the predetermined intervals based on the angle of inclination.

摘要： An optical scanning device, which comprises a light source unit, a scanning unit for scanning a scanning surface with a light from the light source unit in a first direction and a second direction orthogonal to the first direction, and an optical unit for guiding the scanning light onto the scanning surface. The scanning unit has a deflection surface which sine-wave-drives in the first direction. The optical unit has an optical surface whose arbitrary cross section in the first direction has a shape where a second order derivative of the function representing a shape of the cross section changes so as to diverge a light stronger as toward the periphery from the center. And the optical surface is configured by arranging the shape of each cross section in the first direction in the second direction.
