Abstract: An optical scanner includes a light source including light emitters, an aperture member collimating light beams from the light source, a deflector deflecting the light beams passing through the aperture member, and a scanning optical system condensing the deflected light beams onto a scanned surface to optically scan the surface in a main-scanning direction. The scanning optical system includes a resin scanning system having at least one resin scanning lens. At least one folding mirror/sheet glass is disposed between a scanning lens nearest to the deflector in the resin scanning system and the scanned surface. At least one scanning lens in the resin scanning system has an uneven birefringence distribution with respect to a sub-scanning direction. An optical conjugate image of the aperture member is formed between a lens surface nearest to the deflector in the resin scanning system and a lens surface nearest to the scanned surface with respect to the sub-scanning direction.

Abstract: An optical scanning system for a K station includes a resin scanning lens and three reflecting mirrors. Two reflectance ratios are calculated: one being the reflectance ratio of a luminous flux traveling toward the scanning start position of a drum-shaped photosensitive drum and the other being the reflectance ratio of a luminous flux traveling toward the scanning end position of the photosensitive drum. The magnitude relation between the two reflectance ratios is such that the reflecting mirror has an inverse magnitude relation to that of the other reflecting mirrors. Moreover, the difference is calculated between the largest value and the smallest value of the reflectance ratio, where the reflectance ratio depends on the angle of deviation of the polygon mirror. The reflecting mirror has the largest difference among the three reflecting mirrors.
