ABSTRACT:
A laser beam source is driven to emit a laser beam for use in scanning an image recording medium in order to record image information thereon in a plurality of exposure areas. The areas are spaced at intervals in a scanning direction in which the image recording medium is scanned by the laser beam. A first current supply source is responsive to an exposure signal for supplying the laser beam source with an exposure current of a higher in level than a threshold level of the laser beam source. A second current supply source supplies a bias current to the laser beam source when the scanning position of the laser beam source is a linear distance ahead of an exposure start position for each area to be exposed, the first and second current supply sources being connected parallel to each other.
