PROBLEM TO BE SOLVED: To make a toner container excellent in the preservable property of toner and to prevent the bursting and the deformation thereof from occurring because of peripheral atmosphere by providing a toner housing body having flexibility at one part and a toner housing body protection member provided outside the toner housing body so that one part is set to leave space for the expansion of the toner housing body in between and constituted so that a ventilation feasible state can be obtained. SOLUTION: The toner container 10 is equipped with a bottle-like toner housing body protection member 15 whose upper end is opened and which is also provided with a partial aperture 16 near the center of the bottom surface and the toner housing body 12 which is arranged inside the protection member 15, whose part near the upper-end open part is fixed to the protection member 15 and whose lower side surface is provided with bellow-like structure. Besides, the housing body 12 is made of resin and arranged by leaving the sufficient space 17 between the bottom surface of the protection member 15. Since the bellow-like structure elongates and contracts, the container 10 can sufficiently cope with the increase of the volume of the inside of the housing body 12 even when the internal pressure of the housing body 12 becomes higher than peripheral pressure because the peripheral pressure becomes low. Besides, the internal pressure of the protection member 15 and the peripheral pressure become equal by the sufficient space 17 and the aperture 16. |
