Agitating and supplying device and a mold for molding same

An agitating and supplying device for being rotated around a central rotary axis in a developing apparatus for transferring a developer in the direction of the central rotary axis while agitating the developer and for supplying the developer onto a developer roller in a direction radially of the central rotary axis, said device comprising:

• a pair of end supports spaced in the direction of the central rotary axis and having shaft receiving holes therein along the central rotary axis and adapted to receive a rotary shaft therein and further having an outer periphery;
• a plurality of straight elongated first supplying members for supplying the developer onto the surface of the developer roller and positioned at circumferentially spaced positions around the central rotary axis and each having one end fixedly connected to the outer periphery of one of said end supports and having the other end fixedly connected to the outer periphery of the other end support, said first supplying members having substantially radially extending surfaces;
• and
• a plurality of second supplying members for transferring the developer in the direction parallel to the central rotary axis, each of said second supplying members having a transfer surface extending in a direction around the central rotary axis generally spirally inclined to the central rotary axis, each second supplying member being connected at one end of the transfer suface thereof to one of said first supplying members adjacent thereto and the second supplying member being connected at the other end of the transfer surface to another of said first supplying members adjacent thereto, successive second supplying members being generally spirally aligned with the preceding and succeeding second supplying members in the succession for extending generally in a spiral around the central rotary axis the connections to said first supplying members being the connections for supporting said second supplying members in said device.
