摘要： A scanning optical device includes a light source for emitting laser light, a rotatable polygonal mirror for deflecting the laser light emitted from the light source, a detecting portion for outputting a detection signal on the basis of incidence of the laser light deflected by the rotatable polygonal mirror on a light receiving surface, and an outputting portion for outputting a driving signal for driving the light source on the basis of output timing of the detection signal and an output period in which the detection signal is outputted. The laser light is emitted depending on an image signal inputted at timing based on output timing of the driving signal. When the output period is longer than a first period, the outputting portion outputs the driving signal on the basis of the output timing of the detection signal and a fixed second period.
