ABSTRACT:
In an optical scanning apparatus, an optical element has power for predominantly correcting a position of a scanning line by scanning in a sub-scanning direction; a scanning line curvature adjusting unit adjusts a curvature of the scanning line by deforming the optical element in the sub-scanning direction; a scanning line inclination adjusting unit adjusts an inclination of the scanning line by rotating the scanning line about an axis that is at right angles to a main scanning direction and the sub-scanning direction; and one automatic actuating unit each provided in the scanning line curvature adjusting unit, and the scanning line inclination adjusting unit.
