Abstract
A toner cartridge includes a shell, a sleeve and a knocking block. The shell has an internal space, an opening communicating with the internal space and exterior of the shell, and an imaginary axis. The shell is rotatable about the imaginary axis. The sleeve is disposed at an outside of the shell and includes an internal path extended along an imaginary line not parallel to the imaginary axis, and two stopping portions located at two ends of the internal path. The knocking block is accommodated in the internal path, and movable along the internal path to knock the stopping portion when the shell rotates, so as to vibrate the shell, so that the carbon powder sticking on the inner wall of the toner cartridge can be shaken off and then discharged by the toner cartridge. Therefore, the remnant carbon powder in the toner cartridge is effectively decreased.
