<P>PROBLEM TO BE SOLVED: To suppress a manufacturing cost and reduce a size of an optical scanning device. <P>SOLUTION: In an optical scanning device which includes: a semiconductor laser for emitting a light flux; an MEMS mirror that has a swing axis, reflects the light flux emitted from the semiconductor laser while reciprocally swinging at a predetermined swing angle around the swing axis, and deflects and scans the reflected light flux at an approximately constant speed; and an imaging optical system for forming an image of the deflected and scanned light flux on a surface to be scanned, a control section 60 includes an exposure control section 61 for controlling the optical scanning device and a storage section 62 for storing a rotational displacement of the center of the swing angle of the MEMS mirror with respect to an optical axis of the imaging optical system. The exposure control section 61 corrects a write-out timing on the surface to be scanned according to the rotational displacement, and controls a light-emitting timing of the semiconductor laser. <P>COPYRIGHT: (C)2013,JPO&INPIT |
