Laser beams LK and LY are respectively emitted from laser diodes,K and,Y and incident on a mirror face of a polygon mirror,via collimator lenses,K,,Y and first cylindrical lenses,K,,Y. The laser beams LK and LY are reflected off the polygon mirror,and deflected. Incidence angles of the laser beams LK and LY are set so that the laser beams LK and LY intersect with each other at a position P which is located before the polygon mirror
