PROBLEM TO BE SOLVED: To improve the stirring effect of toner and also to surely stir recovered toner whose flowability is poor by forming plural projecting and recessing parts so as to be respectively provided with phase differences at the top end parts of plural sheet-like stirring members. SOLUTION: The plural recessing parts 326a and projecting parts 326b are respectively alternately formed at the top end parts of a first sheet-like stirring member 323a and a second sheet-like stirring member 323b. The phase difference is provided between the projecting and recessing parts formed at the first sheet- like stirring member 323a and those formed at the second sheet-like stirring member 323b. In the case of using toner such as the recovered toner whose flowability is poor, a part where the projecting part 326b at the first sheet-like stirring member 323a passes is stirred, and the toner at the part corresponding to the recessing part 326a is not stirred, so that the toner is made in a stripe state. Next, when the second sheet-like stirred member 323b passes, a toner part remaining in the stripe state is stirred by the projecting part 326b of the second sheet-like stirring member 323b by the phase difference of the projecting and recessing parts. |
