An image forming apparatus is provided which is capable of preventing a drop in productivity even if a consumable such as toner is not replenished as expected. The image forming apparatus has a feature of shifting to a mode of saving the consumable if an arrival time of the consumable is determined to be later than a time when the consumable needs to be replenished, on the basis of the shipping status information on the consumable obtained from a management server and the calculated time when the consumable needs to be replenished.
