Abstract

A developing device including a device body which has a toner reception port and supplies toner stored therein to a photosensitive member, a toner cartridge, which is detachably mounted in the device body has a toner discharge port opposed to the toner reception port, and supplies toner stored therein to the device body through the ports, and a cartridge toner cover which has a side that is connected to the device body without the gap.
When the toner cartridge is removed from the device body of the developing device to the toner cover, the toner left in the toner cartridge doesn't leak out the gap between the toner cartridge and the cartridge cover and the surrounding of the developing device isn't soiled with the toner.
