ABSTRACT:
A light scanning device includes: a light deflector deflecting and scanning light modulated by an image signal, and a member to which the light deflector is connected, wherein a portion of the member has an elastically deformable portion, a mass body is mounted to the elastically deformable portion, and a dynamic vibration absorber is formed by the elastically deformable portion and the mass body. Vibrations of the light scanning device can be reduced by the dynamic vibration absorber formed by the elastically deformable portion and the mass body. Image imperfections caused by the vibrations can be prevented.
