Abstract:
1. An image forming apparatus, comprising: a light source to emit laser light; a photoreceptor built in the light source to detect incident light; a deflector configured to deflect the laser light into a scanning laser beam; and a controller configured to control the light source to light on and off, to obtain 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, and to determine 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; wherein the controller determines the laser light emission amount of the light source to be zero during the time period when the path of the laser light from the light source is headed to the reflection surface of the deflector at an incident angle of approximately ninety degrees.
