摘要： 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： An optical scanning apparatus includes a light source, a light source driving unit that turns on the light source according to image information, a deflector that deflects and scans a light beam emitted from the light source according to sinusoidal vibration, and a scanning/imaging optical system that guides the light beam from the deflector to a scanned surface. The scanning/imaging optical system satisfies two conditions, i.e., (1) provided that the deflector moves in such a manner that an angular velocity is constant, linearity is made larger at a most peripheral image height than at a central image height within a range of an effective writing width, and (2) when a deflection angle of the deflector has a sinusoidal characteristic, the linearity is made smaller at the most peripheral image height than at the central image height within the range of the effective writing width.
