ABSTRACT:
An optical scanning device that includes: a light-emitting unit that emits laser light to a polygon mirror on the basis of a turning-on signal; a sensor unit that detects laser light reflected by the polygon mirror and outputs a sensor signal; and a noise removing unit that outputs a laser light detection signal when the sensor signal is output during an output period of the turning-on signal.
