Abstract
A method of manufacturing a light scanning apparatus, including: forming an optical box having a plurality of protrusions arranged along a longitudinal direction of a reflection mirror and provided at positions corresponding to one end side and the other end side of the reflection mirror in the longitudinal direction, respectively; processing protrusions except protrusions that are used for supporting the reflection mirror so that the protrusions except the protrusions that are used for supporting the reflection mirror on the one end side and on the other end side of the reflection mirror are out of contact with the reflection mirror; placing the reflection mirror on the protrusions that have not been processed in the processing; and fixing the reflection mirror, which has been placed on the protrusions that have not been processed in the placing, to the optical box.
