<p>PROBLEM TO BE SOLVED: To provide an image forming device in which image quality is improved by decreasing a space between dots while suppressing the complexity or the cost increase of the device, complexity of image data processing or the lowering of a processing speed, etc., and avoiding the deterioration of resolution of an image to be printed. SOLUTION: An exposure part modulates a light beam by driving an AOM(acousto-optic modulator) with an AOM driver 15 on the basis of line data consisting of a plurality of pixel data, and carries out a scanning exposure to photographic paper. A transportation part drives a micro step motor to move the photographic paper in a direction crossing the scanning direction of the light beam. A control part 30 vibrates an image forming position on the photographic paper in the moving direction of the photographic paper while the exposure part carries out light beam scanning.</p> |
