PROBLEM TO BE SOLVED: To correspond without changing the setting of alignment even when space images having different forms of an alignment mark are received. SOLUTION: When the space image is recorded on a recording medium for printing in an image recording part 25, in a mark re-attaching treatment part 23, image processing for attaching an alignment mark of a prescribed form is done for a space image to which the alignment mark of the prescribed form is not attached. Especially, rewriting treatment is done for erasing an original alignment mark to replace it with a new alignment mark. Besides, when a mark re-attaching area including the alignment mark and an additional information writing area are located to overlap each other, an overlap writing treatment for synthesizing the original alignment mark and the new alignment mark is done without erasing the original alignment mark.
