LIGHT SCAN DEVICE AND IMAGE FORMATION DEVICE

摘要

To suppress a change in the angle of the reflection surface of a reflection member that reflects scanning light, a light scan device comprises: a first support (91) for supporting a reflection mirror (65) at one point on one end of the reflection mirror (65) along a longitudinal direction thereof; a second support (92) for supporting the reflection mirror (65) at a plurality of points on the other end thereof; a reinforcement part (80) for reinforcing the structure of a housing (60) for the reflection mirror (65) on the second support (92) side in the longitudinal direction more so than the structure on the first support (91) side; a single first fixing part (71) that is used to secure the housing (60) to an image formation device (10) near the first support (91) supporting the reflection mirror (65) in the longitudinal direction; and a plurality of second fixing parts (72) that are used to secure the housing (60) to the image formation device (10) near the second support (92).
