An image forming apparatus divides image data into a plurality of image regions in a sub-scanning direction and performs predetermined processing on the image data of each divided image region so as to form an image on a recording medium. The image forming apparatus includes: a detection unit (503) that detects whether the image data of the image region is blank data; a storage unit (505) that stores the image data of the image region that has been subjected to detection; and a control unit (408) that controls whether to cause the detection unit (503) to perform the detection depending on a predetermined printing mode. |
