ABSTRACT:
In a toner cartridge for containing toner utilized in a developing unit of an imaging device of the electrophotographic type, a containing part comprises a foldable material such as vinyl. Thus, the container is folded after toner is supplied to the developing unit. Accordingly, the space for the container filled with toner is prevented from becoming dead space. Further, if the material of the container is transparent, it is possible to detect whether or not toner remains inside of the container.
