Abstract
A scanning imaging optical component is used in an optical scanning device which deflects a beam from a light source by a light deflector, condenses the deflected beam toward a surface to be scanned by a scanning imaging optical system, forms a beam spot on the surface to be scanned, and performs optical scanning of the surface to be scanned. The optical component forms at least a part of the scanning imaging optical system, and at least a part of a surface of the optical component other than an effective optical surface is made to be a roughened surface, and roughness thereof is such that: Rmax>0.5 (μm).
