Abstract
PURPOSE:To elevate the quantitative treatment capacity for reproducing a toner, by using a mesh filter show mesh opening is 5-10 times as large as the diameter of toner particles, and making a toner carry or flow along the surface of the mesh filter. CONSTITUTION:A transfer residual 1 component magnetic toner T1 on the surface of a drum 1, which has been scraped by a cleaning blade 3 drops and collects in a wedge-like space 10. Its collected toner T2 receives magnetic force of a magnet roll 7 provided in a sleeve 6, and crawls up to the upper surface from the right side on the outside surface of a circular arc-like mesh screen 8. In its carrying process, the toner drops on the surface of a sheet 7 through the meshes of the screen 8, and the dropped toner T3 enters and collects in a toner collecting conduit groove 72 through magnetic force of a magnetic roll 5. Subsequently, it is carried out by a carry-out conveyor 9 and is returned to a developing device. The meshes of the screen 8 are 5-50 times as large as the diameter of toner particles, therefore, a toner being impalpable powder passes through without causing clogging. Accordingly, according to such a constitution, the quantitative treatment capacity is elevated.
