Abstract

PURPOSE:To supply toner into a developing unit without scattering the toner outside nor soiling the surroundings by adopting a constitution so that an opening whose sealing member is peeled is opened when a housing container fitted to the developing unit is rotated. CONSTITUTION:For supplying the toner 5 in a toner packing structure 31 into the developing unit 30, the cover of the developing unit 30 is removed and the holding part 44a of a holding member 14 holding the housing container 42 on a supplying port 35 is engaged with a guiding groove 37, to be inserted. When a lever is turned counterclockwise, a seal for sealing 46 is peeled from the opening 41 in accordance with the rotation of the housing container 42, because the end part 46a of the seal for sealing 46 is kept by the guiding groove 37, and the opening 41 is moved downward while being opened. At this time, the seal for sealing 46 is peeled from the opening 41 of the housing container 42, in a state where it is sealed in the developing unit 30 and the toner 5 is directly supplied into the developing unit 30 from the opening 41 through the supplying port 35.
