Abstract
A light beam scanning apparatus includes a laser light source emitting a laser beam, an optical system focusing the laser beam emitted from the laser light source onto a rotating photosensitive drum, a beam scan mechanism moving the point of focus of laser beam on the photosensitive drum, in a direction perpendicular to the direction of main scan, a scan line correction mechanism correcting a scan line to a straight line when the scan line is curved.
