Abstract

PURPOSE:To facilitate the correction of scanning distortion which is complicate and requires much cost by providing an optical member which performs converging operation between a light source and a deflector and a parallel plane transparent optical member which is arranged between the deflector and a scanned surface almost in parallel to the scanned surface and corrects scanning distortion. CONSTITUTION:Light converged by the optical member which is arranged between the light source and deflector 4 and performs converging operation is deflected by the deflector 4 and the parallel plane transparent optical member 5 which is arranged between the deflector 4 and scanned surface almost in parallel to the scanned surface corrects the scanning distortion. Namely, the refracting operation and positive field curvature of the parallel transparent optical member 5 are utilized and when the angle of deflection is too large, the correcting operation can not cover the scanning distortion, so this is specially effective to an optical scanning device which uses a scanning optical system where the maximum deflection angle of scanning converged light is relatively small, thereby facilitating the correction of the scanning distortion which is complicate and costs much.
