While fractionation the recovery toner inside the phloem and the above-mentioned phloem fractionation the recovery

摘要

PROBLEM TO BE SOLVED: To reduce the fluctuation of the classification rate of recovered toner and the restriction of layout by classifying the recovered toner by a sieve part by turning a filter means and carrying the recovered toner in the sieve part in a carrying direction while classifying it by turning. SOLUTION: A cylindrical filter means 2 is constituted of the sieve part 2a arranged horizontally and a supporting part 2b turnably supporting the sieve part 2a, and a rib 2b1 cylindrically holds the sieve part 2a. The spiral shape 2a11 of a carrying shape part 2a1 in the sieve part 2a carrying the recovered toner (t) inside the sieve part 2a in the carrying direction while classifying it by turning is a mesh member 2a111 obtained by spirally knitting a wire rod made of resin or metallic wire so as to carry the toner (t) to a downstream direction when the sieve part 2a is rotated in a fixed direction. Therefore, the recovered toner (t) in the sieve part 2a is classified by turning the sieve part 2a even when it is horizontally placed, and the waste toner (tt) which is not classified is carried to an aperture part 2a2.
