RECOVERED TONER CLASSIFICATION DEVICE AND IMAGE FORMING DEVICE PROVIDED WITH THE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a recovered toner classification device stable in the classification of recovered toner, high in the classification rate and capable of forming a high-quality image even in the case of using the recovered toner by forming a sieve part for classifying the recovered toner into a plate member provides with plural holes. SOLUTION: The recovered toner (t) discharged from a discharge port 1a1 connected to a carrying screw 116 or a discharge port 1a2 connected to a screw 117 is fed to a cylindrical filter means 2 through a path 1a11 or 1a21 and a carrying screw 6a. The recycled toner (TT) which can pass through the holes 3b provided on the plate member 3a of the sieve part 3 drops onto a recovering coil 9 and is recovered to a recycled toner container 4 through a recycled toner carrying path 4a and a recovery port 4a. Meanwhile, the waste toner (tt) which can not pass through the holes 3b drops onto a recovering coil 10 and is recovered to a waste toner container 5 through a waste toner carrying path 5a and a recovery port 5b.
