PROBLEM TO BE SOLVED: To process the whole of a system at high speed at the time of continuous printing of a plurality of monocolor original by changing over the method of use for an image memory based on the image memory for the portion of original size for a plurality of color components respectively and also the discrimination results of a discrimination means for discriminating whether a formed image is monocolor or full color. SOLUTION: In case of a full color original, all memory use status flags are set after a memory is vacated (S503). Drawing is carried out by using fall memory, and printing is carried out by read data out of the memory and passing through all the flags using memory (S506). In case of a monocolor original, the flags using the memory are set after anyone of memories divided into four is vacated, and color is specified to a corresponding color recognition byte, and drawing is carried out continuously (S510). After the completion of drawing, printing is carried out in monocolor, and corresponding flags using the memory are dropped at the time of completion (S512). In case of continuation of use of monocolor original in the above-said flow, printing and drawing are carried out in parallel with by finding a vacated memory for use. |
