Abstract
A developing device includes a developing container, a first stirring and conveying member, a second stirring and conveying member, a developer replenishing port, a developer discharging portion, a developing roller, a toner supply roller, a regulating blade, a toner receiver member, and a vibration generating device. The developing device is capable of executing a toner collecting mode in which the vibration generating device vibrates the toner receiver member so that toner deposited on the toner receiver member is shaken off by vibration and is collected into the second conveying chamber, in the non-image formation period. The developing device is capable of executing a forced discharge mode in which developer containing the collected toner collected from the toner receiver member into the second conveying chamber is forcibly discharged from the developer discharging portion to outside of the developing container, after the toner collecting mode is executed.
