Abstract

An optical scanning apparatus includes an optical scanning unit which includes a first light source, a first rotatable polygonal mirror for reflecting the beam emitted from the first light source, a second light source, a second rotatable polygonal mirror for reflecting the beam emitted from the second light source; and a housing accommodating the polygonal mirrors. The housing includes only three fixed portions fixed to a fixing portion for fixing the optical scanning unit. The first rotatable polygonal mirror and the second rotatable polygonal mirror are disposed such that a rotational axis of the first rotatable polygonal mirror and a rotational axis of the second rotatable polygonal mirror are in a triangular area defined by lines connecting the three fixed portions, as viewed in a rotation axial direction of the first rotatable polygonal mirror.
