IMAGE FORMING DEVICE AND PHOTOGRAPHIC PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To secure excellent image quality without using an accurate fθlens. SOLUTION: A laser beam scanning unit 100 is equipped with a laser beam source l04R or the like, and a scanning optical system performing scanning the image forming spot of a reflected beam by rotating a polygon mirror 118 with respect to an incident beam from the laser beam source and time- sequentially angling the reflected beam, and is equipped with a bending means for bending photosensitive material 1 along the scanning direction of the image forming spot in the case of exposing photosensitive material 1 with the reflected beam to be scanned.
