Abstract
A developing device includes a developer container, a first stirring member, a second stirring member, and a developer carrying member. The second stirring member includes a second transport blade for transporting developer inside a second transport chamber; a regulating portion having a first regulating blade formed next to, downstream of, the second transport blade in the transport direction of the developer inside the second transport chamber, for transporting developer in the same direction as the second transport blade with a smaller transporting force than the second transport blade, and a second regulating blade formed next to, downstream of, the first regulating blade for transporting developer in the opposite direction to the first regulating blade, and a discharge blade formed next to, downstream of, the second regulating blade for transporting developer in the same direction as the second transport blade to discharge the developer through the developer discharge port.
