Abstract
The object is to carry out developer feeding and toner supplement in a short time without scattering dust particles around, in view of the effectual use of natural resources and space saving. A developer cartridge is removably mounted on a developing unit body and also functions as a lid for closing a developer supply opening after developer has been released into the developing unit body. A toner cartridge includes a lid which can be inserted into and taken out of a toner cartridge body; a sealing member for sealing the toner release opening of the toner cartridge body, the leading edge of which is fixedly attached to the end of the lid on a side from which the lid is inserted; and a tab sheet one end of which is fixed to the middle position of the sealing member and the other end of which is temporarily affixed to the lid. When the sealing member is stripped off, the tab sheet is pulled after the lid has been pulled out as far as a specified position, whereby the sealing member can be folded in two with the toner sticking face inward.
