A light scanning system is provided that includes a light source unit emitting light, and a light deflector having a sinusoidally vibrating deflecting surface that deflects and scans the light emitted from the light source unit. When the deflecting surface is positioned to direct light to the center of a scan range, the maximum deflection angle Phi<SUB>0 </SUB>of the deflecting surface satisfies 20°<=Phi<SUB>0</SUB><=25°.
