Abstract

PURPOSE:To make possible high-performance cleaning without soiling the inside of the machine by providing a driving member to a recovered toner conveying screw provided in a toner collecting member, and oscillating a metal fitting mounted with a guide plate by means of said member. CONSTITUTION:A toner collecting member 9 is disposed below a blade housing 2, and a recovered toner conveying screw 11 formed with a cam 10 at one end is provided therein. Also, a guide plate 14 for receiving the falling toner and conducting the same to the screw 11 is mounted to a metal fitting 12 which is supported by a side plate A oscillatably by a fulcrum shaft 13, is abutted at one end part to the cam 10 and oscillates perpendicularly according to the turning of the cam 10 on the upper stream side of the drum movement of a blade 3 scrapping off the residual toner stuck to the surface of a photosensitive drum 1. Thereby, the cleaning may be accomplished at high performance without contaminating the inside of the copying machine with the toner.
