Abstract
An image forming apparatus is provided. The image forming apparatus includes a semiconductor laser that emits a laser beam, a light power of the laser beam being controllable by a current applied to the semiconductor laser; a scanner unit that exposes a photosensitive element by scanning the photosensitive element using the laser beam; a light power detection unit that detects a light power of the laser beam; a current control unit that controls the current applied to the laser based on the light power of the laser beam; a home position detection unit that detects whether the laser beam is positioned at a scan home position; and a continuous illumination unit that commences continuous illumination of the laser at a time which is prior to a forecast time at which the home position detection unit is forecast to detect the laser beam.
