PURPOSE:To reduce the number of parts, to obtain easy-to-assemble constitution, to reduce cost, to drop toner adhering to the inner surface of a dropping path so as to prevent the accumulation of the toner, and to eliminate the clogging of the dropping path by the toner in an electrophotographic recording device in which removed residual toner on a photoreceptor is recovered through the dropping path. CONSTITUTION:In a toner recovering device 20, a nearly horizontal carrying path 28 is provided to be coupled with a cleaning device, the nearly perpendicular dropping path 29 is provided to turn downward from the edge part of the carrying path 28, and a carrying path 30 is provided in parallel with the carrying path 28 from the lower part of the dropping path 29 and coupled with a discharged toner tank 25. Carrying screws 34 and 35 are arranged in the carrying paths 28 and 30. A sphere 40 is arranged in contact with a carrying screw 35 in the dropping path 29. At the time of recovering the toner, the toner adhering to the inner surface 29a of the dropping path 29 is dropped by moving the sphere 40 by the rotation of the screw 35 in the carrying path 30 and allowing it to collide with the toner. |
