Abstract
A scanning optical apparatus for a printer and a digital copying machine has a light source, a deflector, first and second imaging units. The deflector deflects a light beam emitted from the light source to a main scanning direction. The first imaging unit makes the light beam emitted from the light source form an image in the vicinity of the deflection position of said deflector in the sub-scanning direction. The first imaging unit has a first resin lens having a negative refractive power only in a sub-scanning direction. The second imaging unit makes the light beam deflected by the deflector form an image on a scanned surface in the sub-scanning direction. The second imaging unit has a second resin lens having a positive refractive power only in the sub-scanning direction.
