    摘要： An optical scanning device includes a plurality of scanning optical systems that focus light beams deflected by an optical deflector onto corresponding scanning surfaces. The systems include a first scanning optical system and a second scanning optical system. The first scanning optical system and the second scanning optical system are disposed respectively at each side of a plane including a rotation axis of a polygonal-mirror optical deflector. Each of the scanning optical systems includes a synchronous detection optical system that determines a timing to start scanning the scanning surfaces with the light beams. When a time from the end of an effective scanning area in the second scanning optical system to synchronous detection in the first scanning optical system is Ta, and a time from the end of an effective scanning area in the first scanning optical system to synchronous detection in the second scanning optical system is Tb, Ta>Tb.

    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.
