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 in which the light energy distribution takes the form of a normal distribution, a 1st scanning unit which causes the light beams produced by the light source to scan in a 1st direction with respect to a photosensitive body, a 2nd scanning unit which causes the light beams produced by the light source to scan in a 2nd direction that is normal to the 1st 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 1st and 2nd directions and a light source lighting control means which connects to and lights the light source and which alters the beam dot diameter by altering the normal distribution of the light beam of the light source.
