Abstract
A toner cartridge includes a barrel having an opening, a transmission cap rotatably disposed to the barrel and blocking the opening, a sealing tape, and a toner conveying shaft rotatably disposed inside the barrel. The transmission cap has an outlet and an inner drive portion. The sealing tape has a first end sealing the outlet, and a second end fixedly mounted to the barrel. The toner conveying shaft has a driven portion. During a rotational period of the transmission cap, the first end of the sealing tape detaches from the outlet first, and then the inner drive portion abuts against the driven portion. When the transmission cap continuously rotates, the toner conveying shaft is driven by the transmission cap to rotate. As such, the transmission cap can drive the toner conveying shaft to synchronously rotate after the transmission cap brings the sealing tape to detach from the outlet.
