Dust collecting boxes are disposed to the front and rear of the rotational cleaning member, and each of these dust collecting boxes is always urged by spring members in a closing direction thereof. Furthermore, a locking mechanism for imparting a prescribed damping resistance to the dust collecting boxes during opening and closing operations thereof and for maintaining an opened state thereof when the opening operation is completed is provided.
