PURPOSE:To prevent an elastic sheet from being bent with toner pressure even when the toner pressure rises in a toner container by forming a member for receiving pressure to be exerted from the toner to the elastic sheet. CONSTITUTION:A barrier wall 21 adjacent to an elastic sheet 8 protruding on its right side, that is, into the right side space 5c of a vessel 5 continuously extends throughout the whole length of the sheet 8. Even when high pressure acts on the sheet 8 from the toner in the toner container 5a, it is received with this barrier wall 21. Accordingly, the sheet 8 is not deformed in the right side direction, and a comparatively bendable and deformable sheet can be used as said elastic sheet 8. |
