Abstract

See full text

An image forming apparatus includes an image bearing member; a developing device; a supply device that supplies the developing device with toner; a density detector that detects information about a toner density serving as a ratio of toner and carrier of the developer of the developing device; and a controller that is able to execute a remaining amount determination mode which interrupts the image forming operation and performs a toner supply operation on the developing device from the supply device, based on the detection result of the density detector. The controller at least selectively executes a first state that immediately prohibits the image formation, a second state that allows the image forming operation, and a third state that executes the mode again, based on the detection result of the density detector acquired after the start of execution of the mode.
