PROBLEM TO BE SOLVED: To provide a light scanner in which the bow of a scanning line is corrected without using an expensive optical component. SOLUTION: In a light scanner 10 in which a light beam emitted from a laser beam source 11 is reflected and scanned with a scanning mirror 13, the scanning angle of the scanning mirror 13 is detected with a scanning angle detection part 14, a light emitting timing control part 16 corrects the light emitting timing on the basis of image data in an image data base 17 and correction data which are made on the basis of the actual emitting direction of the light beam calculated with a bow correction part 18 by using a rotational matrix, the light emitting timing control part 16 drives a light emitting driving part 12 when corrected scanning angle information is inputted, so that the light beam is emitted from the laser beam source 11.
