In an optical scanning apparatus having a light source, an incidence optical system for causing a beam emitted from the light source to be incident on a deflector, an imaging optical system for causing the beam reflected and deflected by the deflector to be imaged on a surface to be scanned, and a reflecting portion having a plurality of substantially plane reflecting mirrors disposed in an optical path between the deflector and the surface to be scanned, the reflecting portion includes a reflecting mirror of which the refractive power in a main scanning cross section is of an opposite sign. Provided are an optical scanning apparatus which does not involve structure and work for adjustment, and can obtain stable imaging performance by a simple method even if a plurality of mirrors are disposed, and an image forming apparatus using the same.
