摘要： An image forming apparatus capable of properly performing an initialization of a control circuit including a laser diode driver circuit, includes a light source, a photoreceptor, a deflector, and a controller. The photoreceptor is built in the light source to detect incident light. The deflector deflects the laser light into a scanning laser beam. The controller controls the light source to light on and off, and obtains a laser light emission amount of the light source relative to a current flowing through the light source based on a detection of incident light by the photoreceptor. The controller determines the laser light emission amount of the light source during a time period when a path of the laser light from the light source is headed to a reflection surface of the deflector at an incident angle of approximately ninety degrees.
