PROBLEM TO BE SOLVED: To separate substance smaller than the particle size of pulverized toner or normal toner from recovered toner and to prevent an abnormal image by constituting a sieve part for separating the recovered toner of plural kinds of hole groups for separating the recovered toner advanced from an advance port part to plural kinds of size. SOLUTION: The recovered toner (t) discharged from the discharge port 1a of a recovered toner discharge means 1 connected to a cleaning means 72 and a carrying screw 72b is fed to the slantingly arranged sieve part 2a of a cylindrical filter means 2 housed in a case 0a through a path 4 being a transfer part. While the recovered toner (t) advanced from the advance port 2a1 is separated by plural hole groups 2a2 consisting of the group of plural kinds of holes having the same or approximate size for separating the recovered toner (t) to plural kinds of size by turning the sieve part 2a, it is carried in the carrying direction of the aperture part 2a3 for discharging paper powder or the flocculated lump of the toner by the slant where the sieve part 2a is arranged in the sieve part 2a. |
