PURPOSE:To agitate a developer in the rotating direction with respect to a shaft and to enable the axial movement thereof by providing the 1st and 2nd agitating vanes and isolating the two vanes from each other by means of a shielding body. CONSTITUTION:The driving shaft 18 of an agitator 17 is rotated during developing, and the 1st and 2nd spiral vanes 19, 23 are respectively rotated. A developer 24 is conveyed while it is agitated by the rotation of the vane 23. The conveyed developer 24 is fed through an aperture 22 into a cylindrical body 20 and as the vane 19 rotates, the developer is agitated in the direction opposite from the direction where it is fed by the vane 23, and is thus conveyed. More specifically, the developer 24 is agitated and conveyed while it circulates between the outside and inside of the body 20 around the shaft 18. |
