Abstract: An example toner cartridge includes a housing to contain toner and having a toner outlet, a conveying member, a shutter to open and close the toner outlet, a driven coupler to rotate the conveying member and having an extension that extends in an axial direction, and a protruding member including a rotational force receiver installed in the extension so as to move to a protruding position in which the rotational force receiver protrudes from the extension and a retracted position in which the rotational force receiver is received into the extension in conjunction with opening and closing operations of the shutter.

Abstract: An example operation method of an image forming apparatus includes obtaining, from a sensor, an output signal corresponding to a degree of shrinkage of a transporting member that transports a developing agent in a toner cartridge, as the transporting member rotates, determining a state of the toner cartridge based on a characteristic of the output signal, and executing a recovery mode that increases a driving force delivered to the transporting member when determining that the state of the toner cartridge is an abnormal state in which toner is not normally supplied to a developing device.
