PROBLEM TO BE SOLVED: To provide a stator lowering a cost in improving the yield, and to provide a powder shifting pump, a toner feeding device, a re-using toner classification device and the image forming device which prevent a leak of powder toner, shift the toner surely and form an image in high quality by using the stator. SOLUTION: The stator adopting the powder shifting pump, is consisting of a main body 1 without equipping a flange shape part, a cavity part 2 provided inside the main body 1, a helical grove 3 consisting of plural pitches, provided on an outer peripheral face of the part 2, and a hold means 5 being held by the groove shape part disposed on an end face 4 of one hand side or the other side of the main body 1 that the above helical groove 3 is formed thereon. |
