摘要： An optical scanner includes a plurality of light source units, each light source unit outputting a corresponding light beam; a light deflector having a deflecting surface that deflects the light beams output from the light source units; and a scanning optical system that condenses each light beam deflected by the light deflector onto a corresponding scanning surfaces. The light beams output from the light source units make an angle in a sub-scanning direction with respect to a normal to the deflecting surface. At least one surface of the scanning optical system has not curvature in the sub-scanning direction, and is a special surface having different tilt decentration angles in the sub-scanning direction according to a position in the main scanning direction.

摘要： An optical scanning device includes a plurality of light sources, a light deflector, and a single scan lens. The light deflector deflects a plurality of light beams emitted from the light sources by a same face for scanning a plurality of to-be-scanned portions simultaneously. The single scan lens receives the light beams from the light deflector and focuses the light beams onto each of the plurality of to-be-scanned portions to scan the to-be-scanned portions simultaneously. The single scan lens is used in common for the light beams, and has one incidence plane and a plurality of exit planes in a sub-scanning direction separately prepared in the sub-scanning direction for each of the to-be-scanned portions. The incidence plane has a refractive power of the lens in the sub-scanning direction decreasing toward peripheral portions in the main scanning direction. The exit planes have positive refractive power in the main and sub-scanning directions.

摘要： Light beams emitted from a plurality of light source devices are deflected by a shared light deflector. The light beams are respectively concentrated on different scanning subjects using a first scanning lens and second scanning lenses and are used to perform a scan. All light beams make an angle in a sub-scanning direction to a normal line of a reflecting surface of the light deflector. An incidence surface of the first scanning lens is a surface of which a curvature in the sub-scanning direction changes depending on a main scanning direction. The incidence surface of the first scanning lens is also an optical surface of which a negative refracting power becomes stronger toward a periphery of the surface in the main scanning direction.
