Abstract: An image forming apparatus includes a cutter, an image forming section, and a controller. The cutter performs cutting of a print medium on the basis of a cutting instruction. The image forming section performs, on the basis of print data, image formation on the print medium with use of a consumable material. The controller calculates, on the basis of the print data, an estimated use amount on the basis of a section page group as a unit, and determines, on the basis of the estimated use amount and a usable amount, whether the image forming section is able to use the consumable material. The section page group is a page group, of the print medium, sectioned in accordance with the cutting instruction. The estimated use amount is an amount of the consumable material to be used. The usable amount is a remaining amount of the consumable material that is usable.
