は構成が簡易で効果的なりリーニングを口１とするので
汎用されている。Conventionally, in an image forming apparatus in which developed images are formed on an image carrier such as an electrophotographic photoreceptor, and the image carrier is repeatedly used by transfer, a cleaning device is used to remove residues from the surface of the image carrier. Various methods, such as a blade cleaning method, a fur brush cleaning method, and a web cleaner method, have been put into practical use. In particular, the blade cleaning method is widely used because it has a simple structure, is effective, and has only one opening for cleaning.

Further, such rubbing also caused wear on the cleaning member and the toner receiving member. For this reason, in the conventional device, cream;
A safety mechanism was provided to support the toner receiver member and the toner receiver member so that they could move freely, and to separate them from the surface of the image carrier when they were attached or detached. Therefore, when attaching and detaching the cleaning device, it is necessary to operate the safety mechanism, and the tagging device itself becomes complicated.
本発明は、上述の点に鑑み成されたもので、簡易な構成

It is set. In addition, if the center of gravity of the cleaning device is stabilized in the perspective position shown in the figure, the load will be small when it is installed or removed, and it will be easy to change to this state from the set position when it is removed. This shows the state in which the cleaning device has been completely sterilized. In reality, a slight movement distance is provided until the 17mm portion of the guide member 17 reaches the 19B position of the guide groove member 18 and is completely set in the palanquin. In this state, as described above, the guide member 17 moves to the fourth position approximately at the center of the portion 17B regulated by the protrusion 20 of the guide groove member.
The cleaning device itself is rotated counterclockwise in Figure (a) to move it to the photosensitive drum set position. A set stopper 26 is provided at the bottom of the /9-JILy dust station of the main body of the apparatus to prevent the cleaner from coming too close to the /:yu74 optical dot. Further, the back position is defined by a set bin 22 provided on the back side plate of the cleaning device housing.
