ABSTRACT:
An image formation device for forming an electrostatic latent image on a photosensitive body using a semiconductor laser to generate a laser beam, a collimating lens for focusing the laser beam into a parallel beam, a collimating lens unit which is rotatable and arranged to flatten the laser beam from the collimating lens, a polygonal mirror for scanning the laser beam by means of reflecting surfaces, and a first and a second scanning lens for cooperatively scanning the optical path for moving the beam from the polygonal mirror onto the photosensitive body at a constant speed.
