Abstract:
1. A developer-agitating transporter comprising: a plurality of helical blades that helically extend around a rotation shaft, the plurality of helical blades being arranged at different positions in a direction perpendicular to a longitudinal direction of the rotation shaft; and a gap portion that divides each of the plurality of helical blades into a first blade portion and a second blade portion so that the helical blade is discontinuous in a direction in which the helical blade extends, the first blade portion and the second blade portion opposing each other across the gap portion, wherein the gap portion causes the first blade portion and the second blade portion to be arranged at a certain angular interval in a circumferential direction of the rotation shaft, and wherein at least one surface of adjacent ones of the helical blades that are adjacent in the circumferential direction of the rotation shaft has a sloped area that is sloped at an angle that changes with respect to an axial direction of the rotation shaft.
