Abstract: PURPOSE:To compensate curvature of field in the main scan direction and curvature of field in the subscan direction simultaneously only by plane of polarization by making plane of polarization on an optical deflecting system non-spherical surface on which curvature in the main scan direction is convex and curvature in the subscan direction is concave. CONSTITUTION:Beam of light from a semiconductor laser 1 becomes focusing light by a focusing lens 2, enters a cylindrical lens 3, becomes slightly divergent light only in the subscan direction, transmits a half mirror 4, and reaches a plane of polarization 6. Light which is reflected on the plane of polarization 6 is reflected in the half mirror 4 and reaches a photosensitive drum 7. Toric face polygon 5 rotates with a rotary central axis 8 as the center, deflects incident laser beam of light, and scans on the photosensitive drum 7. Simultaneously, curvature of field in the main scan and subscan directions is compensated and image is formed without blurring of focus over all the scan regions by making the shape of plane of polarization 6 the toric face. Thus, it is possible to compensate curvature of field in the main scan and subscan directions and realize the scan optical system which has no optical system at all between an optical deflecting system and scan face by using the toric face polygon 5 as an optical deflecting system.
