A developing apparatus includes a developer vessel that is provided with a first transporting path, a second transporting path and a third transporting path. The first transporting path and the second transporting path are communicated with each other, and a developer is circulated in the first transporting path and the second transporting path. The third transporting path is provided in an upstream side in a transporting direction of the developer in the second transporting path. If a toner is consumed while forming an image on a paper, a toner corresponding to a consumption amount is resupplied together with a carrier from a toner cartridge to the developer vessel. A carrier and/or a developer that overflows from the second transporting path to the third transporting path is discharged from a discharge port. |
