Abstract
A developing device includes a developer container including a first chamber and a second chamber arranged along a lateral direction, which crosses a gravitational direction, developer circulating through the first chamber and the second chamber; a transporting member rotatably disposed in the first chamber; and a supply member rotatably disposed in the second chamber. A lower end position of the supply member and a lower end position of the transporting member in the gravitational direction are at the same level. While the supply member and the transporting member are rotating, an upper surface of developer contained in the first chamber and an upper surface of developer contained in the second chamber are at levels not higher than an upper end position of the transporting member but not lower than an upper end position of the supply member in the gravitational direction.
