An image-forming system prevents a print overrun error even if there are bands of divided data having different band heights. An image-forming system has a band divider to divide image data into a plurality of bands each containing divided image date, a loader to load the bands into a band memory, and an output unit to sequentially output the bands from the band memory to a print engine at predetermined timing. The band divider can change the height of at least one of the bands from the height of the remaining bands. The band memory includes VRAMs into which a band of bitmap data whose band height is higher than a threshold is loaded and an auxiliary VRAM (VRAM-special) into which a band of bitmap data whose height has been changed.
