Abstract

PURPOSE:To enlarge the contained volume of a cleaned image forming material and to miniaturize the entire device by providing a push-in-means for pushing the returned image forming material into a containing chamber together with a gauge member installed on the opening of the containing chamber. CONSTITUTION:The gauge member 70 is installed on the overall opening 41 for pushing toner into the containing chamber 40 along an inner wall, and fixed to the periphery of the opening 41. When a push-in-body 42 rotates to carry out an pushing-in action, an elastic member 44 is pushed to the gauge member 70 to be bent, and due to pressure force at said time the toner T is pushed into the containing chamber 40 through the gauge member 70. Thus a large amount of the image forming member can be contained without scaling up the overall device, and checking and maintenance can be facilitated with easy unification.
