Abstract
A transport member includes: a shaft portion having a linear portion that is linearly disposed along a linear section of a transport path, and a curved portion that is curvedly disposed along a curved section of the transport path; and screw blades that are spirally formed on an outer circumferential surface of the linear portion and the curved portion, and that transport a powder material by rotation of the shaft portion in one of axial directions of the shaft portion, the screw blades having a small-diameter portion which has an outer diameter smaller in the curved portion than in the linear portion.
