Abstract
A scanning optical device includes a light source unit, a deflector for deflectively scanning a light beam from the light source unit, a photodetector, and a compound optical system. In the compound optical system, a first optical system for guiding the light beam from the light source unit toward the deflector, and a second optical system for guiding the light beam deflectively scanned by the deflector toward the photodetector are integrally formed. The compound optical system is so held as to be movable in a direction other than an optical axis direction of the first optical system.
