Abstract:
A scanning optical device comprising:light source means having a plurality of light emitting points;deflection means for deflecting a plurality of light beams emitted by said light source means; andan optical system for guiding the plurality of light beams emitted by said light source means onto a surface to be scanned,wherein said device satisfies the following relationships: ##EQU4##where n is a positive integer, where L is a light emitting interval between the plurality of light emitting points, .theta. is a tilt angle of the plurality of light emitting points, juxtaposed in a main scanning direction, and inclined in a subscanning direction about an optical axis as a center, P is a beam interval of the plurality of light beams in the subscanning direction on the surface to be scanned, and .beta..sub.S and .beta..sub.F are respectively imaging magnifications of said optical system in the main and subscanning directions.
