摘要：A scanning optical device includes at least one light source unit for emitting alight beam, a first deflector for deflecting the emitted light beam in an auxiliary scanningdirection, a condensing optical system for generating an intermediate image of the lightbeam deflected by the first deflector, a collecting optical system for condensing a light
beam diverged from the generated intermediate image, a second deflector for
deflecting the condensed light beam in a main-scanning direction, and a scanning opticalsystem for scanning the surface to be scanned with the light beam deflected by thesecond deflector. The condensing optical system has an f-θ characteristic, the collectingoptical system has an f-sin θ characteristic, and the scanning optical system has an f-sin θcharacteristic.
