An optical scanning device is provided with a light source, a scanning system, a light receiving unit having a plurality of light receiving elements arranged in a main scanning direction, a resonance amplifying system that amplifies the light receiving signals of the light receiving elements. A clock signal is generated based on the resonance amplified signals. Further, a delay signal is generated to wait for stabilization of the clock signal. A synchronizing signal is generated based on the clock signal and the delay signal.
