| 摘要 |
A scanning optical apparatus includes a plurality of rotatable polygonal mirrors for scanningly deflecting laser beams; a plurality of optical members provided across optical paths of the beams deflected by the rotatable polygonal mirrors; vibration detecting means for detecting vibration of at least one of the optical members during driving of the rotatable polygonal mirrors; phase control means for controlling a phase relation between the rotatable polygonal mirrors on the basis of an output of the vibration detecting means.
