<p>In an image forming apparatus, a separating unit (212) separates each laser beam into a first laser beam used for measuring light intensity and a second laser beam used for scanning a photosensitive element, a photoelectric converting unit (218) measures a light intensity of each of the first laser beams and outputs a voltage indicative of the light intensity. A control unit (302) controls a light intensity of each of the laser beams based on a common drive current and a corresponding one of a current, correction value, which is set by each of the laser beams to correct a light intensity of a corresponding one of the laser beams based on a corresponding one of the voltages output by the photoelectric converting unit.</p> |
