ABSTRACT:
A light flux emitted from a light source is split into two by a light flux splitting unit, and these are respectively made incident on upper and lower tiers of polygon mirrors of a deflecting unit which coaxially rotates two polygon mirrors one on the other while being shifted in angles from each other. The respective light fluxes that have been deflected for scanning at mutually different timings by the deflecting unit respectively reach individual photodetectors through a first scanning lens, mirrors, and a second scanning lens as a predetermined light system and carry out main scanning.
