摘要： A developing device includes: a developer carrier that carries toner thereon; a toner supply member that supplies toner to the developer carrier; a development chamber having the developer carrier and the toner supply member; a replaceable toner cartridge that supplies toner to the development chamber and collects toner from the development chamber; and a contact member that is in contact with the toner supply member to form a nip portion. At the time of replacement to the toner cartridge that contains new toner therein, the new toner is supplied from the toner cartridge into the development chamber and is made to pass through a nip portion between the toner supply member and the contact member within the development chamber, and then nip-passed toner is collected from the development chamber into the toner cartridge.

摘要： A developing device includes a developing agent carrying body that carries toner, a toner supply member that supplies toner to the developing agent carrying body, a regulating member that regulates an amount of toner present on the developing agent carrying body, a developing chamber having the developing agent carrying body, the toner supply member and the regulating member, and a replaceable toner cartridge that supplies toner to the developing chamber and collects the toner from the developing chamber. When the toner cartridge is replaced with a toner cartridge storing new toner, the new toner is supplied to the developing chamber from the toner cartridge. The new toner and the toner remaining in the developing chamber are agitated to form agitated toner, and the agitated toner is collected in the toner cartridge from the developing chamber.
