PROBLEM TO BE SOLVED: To obtain roughly the same images having equal image representation even when a resolution (pixel density) is changed. SOLUTION: An exposing intensity of a laser beam emitted from an exposing device 6 is changed in response to the change of a resolution (pixel density) so that a diameter of an exposing spot of the laser beam is changed. As a result, it is possible to obtain roughly the same images having equal image representation even when the resolution (pixel density) is changed. |
