Abstract
In a laser scanning system for an electrophotographic imaging apparatus, a laser beam, emitted from a laser source, is deflected to repeatedly scan a predetermined angle zone. Before the scanning of the predetermined angle zone, the deflected laser beam is received by a light receiving member. A cover member, projected from a housing of the laser scanning system, covers the light receiving member in such a fashion that the incident of the deflected laser beam is prevented from entering at least an upstream side portion of the light receiving member. The cover member allows the light receiving device to receive the deflected laser beam at a position having a predetermined positional relationship with the laser source.
