Abstract

An image forming apparatus includes: a hardware processor that: estimates a remaining amount of toner in a cartridge; registers a required replacement time corresponding to a time required by an operator to replace the cartridge; calculates a toner consumption speed when an image is printed, on the basis of data of the image to be printed and a printing speed when the image is printed; predicts a first timing at which the cartridge reaches a toner runout state during printing of the image, on the basis of the remaining amount of toner and the toner consumption speed; and makes notification for prompting the operator to replace the cartridge at a second timing before the first timing by the required replacement time.
