ABSTRACT:
An optical scanning apparatus for correcting the curvature of a scanning line effectively by a small number or parts, having a rotary polygon mirror for scanning a ray of light, and a reflecting mirror formed over an entire area in the scanning direction of the ray of light, and scanning the ray of light on an image bearing member, the reflecting mirror is nipped and held between a support member for supporting the reflecting mirror and a pressure member for pressing the reflecting mirror toward the support member side, and the pressure member is movable in a main scanning direction.
