A toner discharging device has a toner containing section, a toner discharging member, and a toner discharging section. The toner discharging section has a toner discharge port formed by opening a vertically lower part of the cylindrical wall. The toner discharging member has a rotation axis; a toner discharge plate fixed to the rotation axis at a position facing the discharge port in the vicinity of one end of the discharging section and vertically above the discharge port; an elastic helical blade being fixed, to the discharge plate and being stretchable in a direction of the rotation axis; and a helical blade section having a helical blade fixed to the rotation axis over an area in the vicinity of another end of the discharging section and an area within the containing section where the discharge plate and the elastic helical blade are not formed.
