摘要： An opening for discharging toner is formed in a lower part of a cartridge body containing toner. A shutter mounting body is mounted on the opening. A first shutter is slidably mounted on the shutter mounting body. A second shutter is slidably mounted on the first shutter. A front end of a sealing member for sealing the opening is extended, the extended front end being inserted through a seal traction opening formed in a front end of the second shutter, and fixed to a front end of the first shutter. When the second shutter is pulled out of the shutter mounting body, the sealing member is towed by the seal traction opening. In addition, the first shutter is further towed by the sealing member, to be also pulled out. Consequently, nearly half of the sealing member from its front end is stripped. When the second shutter is further pulled out after the movement of the first shutter is regulated, the seal traction opening in the second shutter tows the sealing member while allowing the insertion of the sealing member. At this time, the sealing member is stripped while being so folded that a toner adhering surface is located in its inside. In this construction, the stroke for stripping is decreased, thereby to make it possible to prevent contamination by toner as well as prevent a large part of the sealing member from being ineffective.
