Abstract: An image forming apparatus capable of controlling an amount of light beam to be a target value even when an emission characteristic of a light source varies. A photosensitive member is exposed to the light beam emitted form a light source. A light receiving element receives the light beam. Voltage for prescribing the driving current is set in a voltage setting unit. A voltage control unit controls the voltage so that the light amount of the light beam received by the light receiving element becomes a target light amount. A determination unit determines a correction parameter for correcting the voltage based on at least the voltage set in the voltage setting unit. A correction unit corrects the voltage set in the voltage setting unit with the correction parameter. A current supply unit supplies a driving current corresponding to the corrected voltage to the light source based on image data.
