An image forming apparatus (1) includes a cutter (14), an image forming section (20), and a controller (60). The cutter (14) performs cutting of a print medium (9) on the basis of a cutting instruction (INS). The image forming section (20) performs, on the basis of print data (DP), image formation on the print medium (9) with use of a consumable material (33, 31, 40, 25, 27, 9). The controller (60) calculates, on the basis of the print data (DP), an estimated use amount (TU) on the basis of a section page group (SEG) as a unit, and determines, on the basis of the estimated use amount (TU) and a usable amount (TR), whether the image forming section (20) is able to use the consumable material (33, 31, 40, 25, 27, 9). The section page group (SEG) is a page group, of the print medium (9), sectioned in accordance with the cutting instruction (INS). The estimated use amount (TU) is an amount of the consumable material (33, 31, 40, 25, 27, 9) to be used. The usable amount (TR) is a remaining amount of the consumable material (33, 31, 40, 25, 27, 9) that is usable.
