Abstract
A light scanning apparatus, including: a light source; a deflection unit configured to deflect a light beam emitted from the light source; a reflecting mirror configured to reflect the light beam to a photosensitive member; a housing; a first support portion provided in the housing to support one end of the reflecting mirror; a second support portion provided in the housing to support the other end of the reflecting mirror; a first leaf spring configured to press the reflecting mirror at the one end to apply an urging force for urging the reflecting mirror against the first support portion; and a second leaf spring configured to press the reflecting mirror at the other end to apply an urging force for urging the reflecting mirror against the second support portion, wherein a pressing force of the first leaf spring is larger than a pressing force of the second leaf spring.
