Waste toner storage container and image forming apparatus that accurately detect an amount of waste toner
A waste toner storage container includes a container body, a toner storage chamber, and a paddle. The toner storage chamber includes an introduction port, a first space, and a second space. The introduction port receives waste toner. The first space stores the introduced waste toner, and extends in a first direction. The second space is disposed in an end portion of the first space in a second direction orthogonal to the first direction. The paddle includes a shaft, a first plate, and a second plate. The shaft is disposed in the first space, extends along the first direction, and is elongated. The first plate is formed on an outer peripheral surface around a central axis of the shaft, and conveys the waste toner in the first direction. The second plate is formed on the outer peripheral surface of the shaft, and conveys the waste toner toward the second space.
