When printing images as ordinary prints on a photosensitive material, index prints are also automatically printed of a same size as the ordinary prints for higher work efficiency. At a projection exposure stage, exposure of a film is effected to obtain ordinary prints using a light source, a lens and a shutter. Also, data of images on the film is read by an optical reader and converted into digital signals. Index prints are then exposed by a PLZT print head which is controlled based on the digital signals.
