When the developing device has reached a toner shortage condition, a toner stortage indication is produced for urging one to supply a fresh toner or to replace a toner cartridge. The toner shortage condition and toner shortage indication are reset only when a predetermined period of time expires from the instant when one opens a door or a cover of the apparatus for the supply of toner to the instant when one closes it after the supply of toner.
