Abstract
An optical scanning device for an electrophotographic printer includes a light source that radiates a light beam and a light deflector that deflects the light beam radiated by the light source in a main scanning direction. The optical scanning device also includes a synchronization detection sensor having a sensing region that receives a portion of the light beam deflected by the light deflector. The sensing region has a greater length in the main scanning direction than in a sub-scanning direction.
