Abstract:
A member for agitating and conveying a developer, includes: a rotation shaft that rotates in a given direction; a spiral-shaped conveying member that is disposed on an outer circumferential surface of the rotation shaft; and conveys a developer in a shaft direction of the rotation shaft; a protruded agitation section that protrudes, with a gap from the rotation shaft, from the spiral-shaped conveying member toward an upstream side in a developer conveying direction; and agitates the developer; and a diameter directional conveying section that is disposed between adjacent spires of the spiral-shaped conveying member; is disposed in a downstream side in the developer conveying direction with respect to the protruded agitation section; and gives a diameter directional conveying force to the developer.
