A developing device for an electrophotographic recorder includes an open-topped container having a toner inlet port; a toner cartridge which can be detachably mounted on the container so that its toner discharge port is opposed to the toner inlet port and supplies toner through the ports to the container, and a toner cartridge cover which is connectible at one end to the container. The toner cartridge is slid from the container on to the cover so that any toner left in the cartridge does not leak out between the cartridge and the cover to soil the surrounding area.
