Optical scanning apparatus and image forming apparatus
Abstract:
Synchronization detecting units detect synchronization signals by receiving the light beam deflected to one side of a light source on one side of an optical deflector and receiving the light beam deflected to an opposite side of an optical axis of a scanning optical system from the light source on the other side of the optical deflector. Photodetectors that detect the synchronization signals are arranged on the opposite side of an optical axis of a scanning optical system from the light sources and on a side closer to the scanning optical system that detects the synchronization signals by receiving the light beam deflected to the light source.
