摘要： An optical scanner is capable of effectively correcting a difference with respect to the sub-scanning direction between the positions of optical spots for scanning photoconductor drums of a tandem type color image forming apparatus. The optical scanner includes an optical axis adjusting part. The optical axis adjusting part uses a deflecting mirror or a wedge-shaped prism to deflect the optical axis of an optical beam with respect to the sub-scanning direction. As a result, it is possible to accurately correct a resist difference among individual image forming stations and form a high-quality color image without any color displacement.

摘要： An optical scanning apparatus includes a housing that positions and holds a plurality of light sources emitting light beams, a deflection mirror that deflects the light beams to perform main scanning, and at least one of optical image forming elements closest to the deflection mirror to form images on respective image carriers. A plurality of reflectors guide the light beams exiting the housing to the respective image carriers. A pair of support members face each other to support the housing in a main scanning direction. A support mechanism supports the reflectors by bridging the reflectors between the support members and also couples the support members to each other. Relative positions of the reflectors are arranged in a cross-sectional plane perpendicular to a main scanning direction between the support members.

An optical deflecting unit deflects the light beam passing through the line-imaging lens. An imaging optical unit images the light beam deflected by the optical deflecting unit in a spot shape on a scanning surface to be scanned. An adjusting unit adjusts a position of irradiation of the light beam from the light-source unit on the optical deflecting unit.
