ABSTRACT:
A light beam scanning apparatus in which light beams are modulated by image information signals and the modulated light beams are directed onto a photosensitive body consists of a light source which produces light beams, a first scanning unit which causes the light beams produced by the light source to scan in a first direction with respect to a photosensitive body, a second scanning unit which causes the light beams produced by the light source to scan in a second direction that is normal to the first direction, an image formation means by which an image constituted by continuous or discontinuous dots is formed on the photosensitive body following scanning in the first and second directions and a speed control means which controls the speed of light beam scanning brought about by the first scanning unit in a manner such that the density of dots successively formed in the second direction is made variable.
