PURPOSE:To prevent the scattering of a toner from a gap generated in a slide- contacting surface between a duct and a vessel entrance part by hermetically shutting the toner by using a molt plane in at least one of the counter surfaces of the duct communicated with a cleaning box, and the entrance part of a toner recovering vessel, which can be oscillated in a horizontal direction. CONSTITUTION:In a cleaning box 46 to be set in one side of a sensitive body drum 40, the toner scraped down from the sensitive body drum 40 by a blade 47 is unidirectionally carried by a screw 47a provided on the bottom part of a cleaning box 47, and received from an edge part through a duct 471 to a recovering vessel 472. This recovering vessel 472 is oscillated in the horizontal direction by the stretching force of a spring 474a and the pressing force of a cam 474b and the recovered toner is prevented from being accumulated in the vicinity of the entrance part of the vessel. A sealing member 476 is provided on the slide-contacting surface between the duct 471 and the vessel entrance part. Then, the gap to be needed for the oscillation is completely shut out. Thus, the toner scattering from a connecting part can be effectively prevented. |
