Abstract
A light scanning device of the invention includes a scan deflection range of each of the light fluxes deflected by the deflecting part in a scan period of the scan object with the respective light fluxes is divided into a first deflection range where a reflection angle of each of the light fluxes with respect to the deflecting part is small and a second deflection range where the reflection angle is large. A polarization direction of each of the light fluxes is set such that a reflectivity of the reflective mirror when each of the light fluxes deflected in the second deflection range is reflected becomes larger than a reflectivity of the reflective mirror when each of the light fluxes deflected in the first deflection range is reflected.
