In an image forming apparatus that exposes a photoreceptor using a laser beam scanning system, there is a detection means that detects light projected onto a part of the main scanning width of a laser beam near the photoreceptor, and a detection means that moves the detection means in the main scanning direction. What is claimed is: 1. A main scanning synchronizing signal generating device for an image forming apparatus, characterized in that the main scanning synchronizing signal generating device includes a moving means for moving light, and easily obtains an appropriate synchronizing signal by adjusting a light detection position.
