发明名称 Multi-beam exposure unit
摘要 This invention has as its object to provide an image forming apparatus which can provide a color image free from any color misregistration with low cost, and a light scanning unit suitable for the apparatus. The apparatus includes a finite lens and a cylinder lens for giving predetermined characteristics to light beams emitted by a plurality of light sources, a laser synthesis mirror unit for synthesizing laser beams passing through the lenses, a deflection unit for deflecting the synthesized light beams, first and second image-forming lenses for adjusting the aberration characteristics, at the imaging position, of the deflected light beam, one or three mirrors for outputting the light beam passing through the image forming lenses at predetermined positions, and can provide a color image free from any color misregistration.
