摘要：
The present invention provides a scanning apparatus for scanning a photosensitive member with laser beams, comprising a scanning optical system having reflection members attached to a driving source and for generating two or more modulated laser beams simultaneously, first reflection members for reflecting the respective modulated laser beams to diverge the laser beams from each other, second reflection members arranged downstreamly of a light path with respect to the first reflection members and for reflecting the reflected laser beams on the photosensitive member, attachment means for fixing the scanning apparatus to a main apparatus and a molded structure for integrally supporting the scanning optical system, first reflection members, second reflection members and attachment means altogether.
