ABSTRACT:
A valve which connects selectably one of a plurality of chambers storing different color developer material therein with a developer housing chamber. The valve has one aperture in communication with one of the chambers and another aperture in communication with the other chamber. A shaft is mounted rotatably in the tube. The shaft has a portion thereon adapted to close one of the apertures in the tube with the other aperture remaining open so as to connect selectably either one of the chambers storing the developer material with the chamber of the developer housing. A seal is interposed between the shaft and the tube for sealing the region therebetween. The seal prevents the escape of developer material from the chamber not connected to the developer housing chamber into the developer housing chamber.
