成装置のクリーニング装置。[Claims for Utility Model Registration] (1) A holding member is provided to be rotatable around an axis parallel to the rotational axis of the photoreceptor, and to be swingable around an axis perpendicular to the swinging axis of the holding member. A metal blade holder is pivotally attached to the blade holder, and an elastic blade made of synthetic resin for peeling off toner remaining on the surface of the photoreceptor is attached to the blade holder, and the tip of the elastic blade is brought into contact with the surface of the photoreceptor. In the cleaning device for an image forming apparatus, the cleaning device is configured to be able to switch freely between a state in which the toner is separated from the surface of the photoreceptor and a state in which the toner is separated from the photoconductor. A cleaning device for an image forming apparatus, characterized in that the elastic blade is closed by a flexible sheet member that comes into contact with the elastic blade and does not contact the elastic blade. (2) The cleaning device for an image forming apparatus according to claim 1, wherein the friction coefficient of at least a contact surface of the flexible sheet member with respect to the blade holder is set to be small.
