Title:
光走査装置及びそれを用いた画像形成装置
Document Type and Number:
Japanese Patent JP5164345
Kind Code:
B2
Abstract:
Disclosed is an optical scanning system and an image forming apparatus, being small in size but able to produce high-quality image outputs, wherein the optical scanning system includes a deflecting device for scanningly deflect a light beam from a light source in a main scan direction, and an imaging optical system for imaging, upon a surface to be scanned, the light beam deflected by a deflecting surface of the deflecting device, wherein the deflecting surface is reciprocatingly moved to reciprocatingly scan the surface in the main scan direction with the light beam deflected by the deflecting surface, wherein a first direction refers to a direction of a phase difference of wavefront aberration in the main scan direction between a marginal ray and a principal ray of the light beam reflected by the deflecting surface at an effective deflection angle of the same corresponding to a largest scan position in an effective scan region.
