Abstract
An image printer includes a projection-exposure section for projecting an image born on a film onto a photosensitive material, an image-exposure section for exposing the photosensitive material based on image information comprised of a plurality of image areas each including color data relating to a plurality of colors, and a transport unit for transporting the photosensitive material through the projection-exposure section and the image-exposure section. The image-exposure section includes a plurality of exposure units for dividing the image information into a plurality of lines and exposing the photosensitive material with switching exposing colors corresponding to the plurality of color data, a moving device for moving the plurality of exposure units and the photosensitive material relative to each other in a direction perpendicular to the lines, and a moving-exposure control unit for controlling operations of the exposure units and the moving device. The exposure control unit is capable of effecting a moving exposure control in which the plurality of exposure units respectively effect exposure operations thereof in a parallel manner.
