An image forming apparatus includes a light source; a separating unit that separates a laser beam emitted from the light source into a first laser beam and a second laser beam; a first photoelectric converting unit that measures a light intensity of the first laser beam and outputs a first voltage depending on the light intensity of the first laser beam; a second photoelectric converting unit that measures a light intensity of the second laser beam, and outputs a second voltage depending on the light intensity of the second laser beam; and a control unit that executes a first light-intensity correction for correcting the light intensity of the second laser beam based on a current correction value and a drive current. The current correction value being a value used for correcting a light intensity of the laser beam based on the first voltage and the second voltage, and the drive current being a current preliminarily-set with respect to the laser beam to cause the light source to emit the laser beam. |
