Abstract
A laser scanning unit to form an electrostatic latent image according to an image signal by projecting a light onto a photosensitive medium. The laser scanning unit has a light source having a cylindrical shape of a predetermined length; a reflective member surrounding the light source to focus the light from the light source; a micro-mirror array to reflect the light focused by the reflective member toward the photosensitive medium; a driving control unit to drive the micro-mirror array according to the image signal; and a micro-lens array disposed in an optical path between the micro-mirror array and the photosensitive medium, to focus the light reflected from the micro-mirror array onto the surface of the photosensitive medium.
