toner cartridge

Abstract

Abstract PURPOSE:To prevent scattering of a toner by rotating longitudinally a winding member from one end of a sealing member which closes hermetically a longitudinally formed opening for replenishing the toner and winding up successively said member. CONSTITUTION:A toner cartridge 1 contains a toner 19 thereon and closes hermetically an opening 2 for replenishing by a sealing member 3. The sealing member of such cartridge is successively wound up by rotating longutdinally a winding member 4 from one end of the sealing member which closes hermetically the longitudinally formed opening for replenishing the toner, thereby opening said opening. The member 4 may be any of paper, plastics, metal or the like and the shape thereof may be either circular cylindrical or square columnar shape as far as the member 3 can be wound. Said winding member is preliminarily attached to the end of the member 3 or is provided to the cartridge body 1 in a removable way so that said member is removed when necessary and is used to wind the top end of the member 3. The member 3 is stripped from the cartridge body while the member 3 is wound by the member 4 in the above-mentioned way, by which the always clean and easy exchange of the cartridge is made possible with less toner scattering.
