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 device for transporting the photosensitive material through the projection-exposure section and the image-exposure section. The image-exposure section includes an exposure device 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 by switching over a plurality of color filters, and a moving device for moving the exposure device and the photosensitive material relative to each other in a direction perpendicular to the lines. The image-exposure section further includes an exposure control unit for controlling operations of the exposure device and the moving device. The control unit effects a moving exposure control for exposing the photosensitive material by switching over the exposing colors while the photosensitive material and the exposure means are being moved relative to each other.
