A laser scanning unit includes a light source, a rotary polygon mirror to deflect a laser beam emitted from the light source, an f-theta lens to image the laser beam deflected from the rotary polygon mirror on a photoconductor, and a flat plate disposed between the light source and the photoconductor to correct a scanning line of the light source. The laser scanning unit can correct an inclination and/or a curvature of a scanning line caused by rotations of the rotary polygon mirror and the photoconductor and other working and assembling processes in order to minimize a deterioration in other performances, thereby allowing product quality to improve.
