PURPOSE:To make possible cleaning with a blade corresponding to a monocolor and to extend considerably the period for maintenance by constituting a cleaning device of plural blades in such a manner that the cleaning blade corresponding to the specific developing device is positioned to a cleaning part. CONSTITUTION:Plural sheets of the blades 21-24 are arranged radially in four sheets by a cylindrical supporting member 25 for holding the blades. A detecting member 6c which detects a developing device for a color toner coopera tively with a detecting means 6b provided on a copying machine body side is attached in the case of executing copying by using, for example, the develop ing device for a red toner. A driving device for rotating the blade is operated by a discrimination circuit from the copying machine body side when said circuit receives the detection signal from the detecting member 6b upon detection of the member 6c. The blade corresponding to the developing device for the red toner is then positioned to the cleaning part. |
