PROBLEM TO BE SOLVED: To provide a classification device for recovered toner which is simple in the constitution of filter means, unlimitedly broad in the fractionation range of a screen part and inexpensive, a process cartridge equipped with the same, a toner supply device and an image forming device. SOLUTION: This classification device is provided with a tubular or polygonal screen part 2a which rotates and classifies the recovered toner (t) which is discharged from a recovered toner discharging means 1 and is stored in a filter means 2, a pillar- shaped floating piece 3 which freely moves the recovered toner(t) in the screen part 2a, inserts the same between an inner peripheral surface 2a1 of the screen part 2a and the floating piece, thereby, extrudes the same to the side of an outer peripheral surfaces 2a2 of the screen part 2a, at the same time, prevents the clogging of the screen part 2a and promotes the classification of the recovered toner(t), and a clearance forming and supporting means 4 which freely-movably supports one end part 3b of the floating piece 3 and the other end part 3c so as to form clearance G between the outer peripheral surface 3a of the floating piece 3 and the inner peripheral surface 2a1 of the screen part 2a. |
