Method of and apparatus for recording image by exposure to light beams

An apparatus recording a two-dimensional image on a photosensitive medium by exposure to light beams which are emitted from a plurality of light sources arrayed in an auxiliary scanning direction and applied to scan the photosensitive medium in a main scanning direction and the auxiliary scanning direction, comprising:

• an image divider for dividing the two-dimensional image in said auxiliary scanning direction depending on intervals between adjacent ones of said light beams emitted from said light sources;
• image storing means for storing images divided by said image divider,
• an auxiliary scanning controller for controlling an auxiliary scanning speed of said light beams in a predetermined range in a recording start area or a recording end area;
• and
• light source driving means for driving said light sources based on the divided images read from said image storing means;
• said auxiliary scanning controller comprising means for increasing or reducing intervals between main scanning lined formed by the respective light beams toward the recording areas of adjacent ones of the light beams in order to correct a displacement of positions recorded by the respective light beams with respect to the auxiliary scanning direction.
