ABSTRACT:
Disclosed is a scanning optical apparatus which can reduce color misregistration in a sub scanning direction to thereby obtain a good color image output, and a color image forming apparatus using the same. In the scanning optical apparatus, a beam emitted from light source means1is deflected by deflecting means5,and the beam deflected by the deflecting means is imaged in a spot shape on a surface7to be scanned by scanning optical device, and light-scans on the surface to be scanned, and a scanning line scanning on the surface to be scanned has two or more extremums within the effective range of a scanning area.
