<p>PROBLEM TO BE SOLVED: To obtain high-quality images by a compact print head. SOLUTION: A plurality of light-emitting elements are arranged in a stagger in a main scan direction, a sub scan direction at a head. While the head is moved in the sub scan direction when a photographic paper on a drum is rotated and transferred in the main scan direction, every 24 light-emitting elements of light-emitting element groups (1)-(4) record image data of the same pixels by 24 times. This multirecording reduces an irregularity of the light-emitting elements and restricts generation of irregular streaks, etc.</p> |
