Abstract
An optical scanning device includes a laser source, an optical deflector which deflects scanning beams emitted from the laser source in a main scanning direction toward an object to be scanned, and a reflecting mirror which reflects the scanning beams. A beam detector which receives the scanning beams reflected by the reflecting mirror and a correcting lens which is provided between the reflecting mirror and the beam detector and which has a power at least in the main scanning direction are also provided. An adjusting lens holder is provided for adjusting the position of the correcting lens in the main scanning direction upon assembly so that an incident timing of the scanning beams onto the beam detector can be adjusted.
