Abstract
A toner cartridge is provided for use in replenishing toner to a toner storing section of an imaging machine, such as a copying machine, which uses toner to produce a visible image. The toner cartridge includes a container having an opening, a folded over seal member having one end fixed to the container and another end fixed to a roller, and means for winding up the seal member which includes a roller provided with a shaft. When the shaft is rotated, the seal member is peeled off the container to unseal its opening. The toner drops from the container into the toner storing section. The seal member can be easily peeled off from the container, and toner is kept from being spilled and from soiling the operator.
