Abstract
A developing device includes: a first transport member and a second transport member that are disposed in a first transport path and a second transport path provided at an upper side and a lower side in a gravitational direction and that transport a developer. The developing device also includes an ejecting path that is provided in the first transport path disposed at the upper side in the gravitational direction and that ejects an excess developer. The developing device includes a reverse helical section that is disposed in front of a support that supports the second transport member. The reverse helical section helically extends in a reverse direction relative to a helical section provided for circulating the developer, the developer being transported to the ejecting path by the reverse helical section.
