Optical scanning apparatus for preventing color misregistration |
摘要 |
An optical scanning apparatus is configured to comprise (a) a deflector for deflecting and scanning a plurality of bundled incident laser beams, (b) a conversion optical system for converting the bundle of laser beams moving at a constant angular velocity into a bundle of laser beams moving at a constant linear velocity, (c) reflection mirrors for separating the bundled laser beams into four corresponding to respective colors, (d) photosensitive members for forming respective electrostatic latent images by means of the laser beams corresponding to the respective colors, wherein one of the photosensitive members is disposed on a plane parallel to an area defined by the laser beams traveling between the deflector and the conversion optical system and (e) a correction optical system for correcting curvatures of field with respect to the respective laser beams and leading the laser beams to the photosensitive members.
