A laser scanning apparatus is provided with a laser diode that is driven to emit a laser beam, a scanning optical system that scans the laser beam emitted by the laser diode on a surface to be scanned, and a controller that drives the laser diode by supplying electrical current to the laser diode. The controller supplies an extra electrical current to the laser diode only at an initial stage of driving of the laser diode so as to cancel an effect of a rising delay of its output intensity.
