An image forming apparatus capable of selecting a toner cartridge from a plurality of toner cartridges containing toner of an identical color preferentially without interrupting an image forming action of the apparatus. When a toner density of the toner in a developer container becomes low, a control section drives a toner supply section in response to information on the remaining amount of the toner contained in the toner cartridges, so that the toner may be supplied from the toner cartridge having the least remaining amount.
