The beam splitter is formed of reflective surfaces and transmissive surfaces. One transmissive surface is disposed between the reflective surfaces in the sub-scanning direction, and an optical path of light beams reaching surfaces to be scanned that are physically closer to the deflection surface than a surface to be scanned located at the position physically farthest from the deflection surface between the reflective surfaces intersects with an optical path of a light beam reaching the surface to be scanned located at a position physically farthest from the deflection surface between the deflection surface and the transmissive surface in a sub-scanning cross section in the beam splitter.

摘要： A scanning optical system using a short-wavelength light of 500 nm or less uses a reflecting mirror having a higher absolute reflectivity and having reduced wavelength and angle dependences. Divergent ray of light emitted from a semiconductor laser is converted into an approximately parallel light beam by a collimator lens and the diameter of the light flux is reduced by an aperture before travel to a polygon mirror. The light beam from the polygon mirror passes through scanning lenses to form a small spot at any point in the entire scanning area. The semiconductor laser is a gallium nitride semiconductor laser having an oscillation wavelength of 408 nm. The polygon mirror has such a characteristic that, if the complex refractive index N of a metallic film contributing to a reflection characteristic of the reflecting mirror is defined as N(λ)=n(λ)−ik(λ), then k(λ)>√{square root over ((−n(λ)2+18n(λ)−1))}{square root over ((−n(λ)2+18n(λ)−1))} is satisfied.
