撹拌・搬送する機能を増大する。The cross section of the spiral blade crossing the length direction has a trapezoidal shape over the entire length. This trapezoidal shape reduces the stress required to agitate and transport toner at each radial position of the spiral blade. Correspondingly, the top is thin and the bottom where a large stress acts is widened, and the cross-sectional area (capacity) of the spiral blade is minimized. This is to maximize the space for storing, agitating and transporting the toner. Further, the trapezoidal shape is gradually changed while the spiral blade goes around the shaft portion, and a thin portion (a portion having a narrow upper portion and a lower portion of the trapezoid) and a bulging portion (particularly a portion having a wider trapezoidal bottom portion). Are formed at a plurality of locations. This enables molding by a molding die, has the effect of reinforcing the spiral blades, and increases the function of stirring and conveying the toner.
