Abstract of the Disclosure A developing device includes 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 in coincidence with the toner reception port, has a toner discharge port opposed to the toner reception port, and supplies toner stored therein to the device body through the ports, a sealing member which is mounted on the device body to surround the toner reception port and seals between the device body and the toner cartridge mounted in the device body, and a pressing mechanism which is provided on the toner cartridge and presses the toner cartridge on the sealing member when the toner cartridge is mounted in the device body.
Cette invention concerne un dispositif révélateur dont le corps comprend un orifice d'admission de toner et sert à acheminer ce produit vers un élément photosensible. Une cartouche de toner fixée de façon amovible dans le corps du dispositif vis-à-vis l'orifice d'admission de toner se raccorde à celui-ci par son embout de refoulement pour permettre l'acheminement de toner dans le corps du dispositif. Un joint d'étanchéité monté sur le corps du dispositif autour de son orifice d'admission prévient les fuites de toner entre celui-ci et la cartouche qui est munie d'un organe de pression l'appuyant contre le joint d'étanchéité lorsqu'elle est montée dans le dispositif.
