A toner discharging device comprising:
- a discharge container comprising a wall portion which defines an internal space thereof and has a reception port for receiving toner and a discharge port for discharging toner;
- and
- a discharge member provided in the discharge container, the discharge member including:
- a rotation shaft, and
- a discharge blade provided around the rotation shaft, the discharge blade moving, according to rotation motion following rotation of the rotation shaft, the toner in the discharge container in a discharge direction that is an axial line direction of the rotation shaft that goes from the reception port to the discharge port, the discharge blade being a decay spiral blade whose lead angle of an outer circumferential portion thereof becomes smaller as advancing in the discharge direction,
- at least a part of the wall portion of the discharge container surrounding the decay spiral blade along the axial line direction of the rotation shaft, and the discharge port being formed on the part of the wall portion.
