A toner conveying device includes a toner conveying section and a toner conveyor. The toner conveying section includes a bent portion and an outlet port. The bent portion bends in a predetermined direction. The outlet port discharges toner. The toner conveyor is bendable and driven by a driving device to rotate to convey toner. The toner conveyor is disposed in the toner conveying section such that a first end of the toner conveyor is coupled to the driving device and a second end of the toner conveyor is a free end. The toner conveyor includes a reverse-flow conveying portion, between the outlet port and the free end, to convey the toner from the second end to the first end.
