Abstract
A transporting member includes multiple helical blades that helically extend around a rotation shaft and that have an upstream-side blade and a downstream-side blade, an end portion of the upstream-side blade and an end portion of the downstream-side blade overlapping in a direction perpendicular to an axial direction of the rotation shaft, the multiple helical blades transporting an object in the axial direction via rotation of the rotation shaft; a gap portion that divides the upstream-side blade and the downstream-side blade, the upstream-side blade and the downstream-side blade being arranged at a certain angular interval in a circumferential direction of the rotation shaft; and a regulating portion that regulates an amount of the object that passes through a space between the upstream-side blade and the downstream-side blade in a direction in which the object is transported.
