An image forming method and apparatus characterized in that current supply periods of time to light-emitting diodes constituting a light-emitting diode arrays are controlled corresponding to gradation levels while a constant current is being supplied to the light-emitting diodes, and in that the current supply period of time is adjusted at every gradation level corresponding to the variations in light intensity of the light-emitting diodes when the constant current is supplied to thereby correct for the variations in output light intensities of the light-emitting diodes.
