A developing device according to the present disclosure includes a developer container, a first stirring member, a second stirring member, and a developer carrying member. The developer container has a plurality of conveyance chambers including first and second conveyance chambers, is provided with a developer supply portion and a developer discharge portion and stores a two-component developer. The second stirring member is provided with an electro-conductive regulating portion that is disposed to oppose the developer discharge portion that regulates movement of the developer to the developer discharge portion. An electro-conductive plate is disposed on an inner wall surface of the developer container that opposes the regulating portion. During rotation of the first and second stirring members, by applying an alternating current bias to at least one of the regulating portion and the electro-conductive plate to generate an electric potential difference between the regulating portion and the electro-conductive plate.
