摘要： A scanning optical device includes a light source, a polygon mirror having a plurality of reflecting surfaces for deflecting a light flux emitted from the light source to form a scanning beam spot on an image surface, an identifying device that identifies which reflecting surface is currently scanning the light flux, a memory that stores data corresponding to shape errors of the reflecting surfaces, a correcting member that corrects a position of the beam spot, and a controller that controls the correcting member in accordance with an output of the identifying device and with data read from the memory. The correcting member is controlled to compensate for deviations of the beam spot due to tilt errors of the reflecting surfaces and may also be controlled to compensate for deviations of the beam spot due to an unevenness of the movement of the image surface.
