Patent ID: 8918032

Claim:
A toner cartridge for an electrophotographic imaging device, comprising: a housing comprising two opposed end walls, an elongated body therebetween and an exit port, the body having an inner surface defining a toner reservoir for containing a quantity of toner, the toner reservoir in fluid communication with the exit port; a drive shaft rotatably mounted within the toner reservoir; a toner platform having a front surface, a rear surface and an edge surface, the front surface for moving toner within the reservoir toward the exit port, the toner platform in slidable contact with the inner surface and movably coupled to the drive shaft, the toner platform being nonrotatable relative to the housing; and a resilient arm positioned within the reservoir and biased toward an initial position in the path of the toner platform, wherein when the drive shaft rotates the toner platform translates toward the exit port for moving toner within the reservoir toward the exit port, when the toner platform contacts the resilient arm the resilient arm moves out of the path of the toner platform to permit the toner platform to pass and when the toner platform moves further toward the exit port the resilient arm returns to the initial position.
