Summary:The utility model relates to a carbon powder tank for a printer, in particular to a feeder of the carbon powder tank, which is characterized in that a filling port is formed on the end of the carbon powder tank, a cylinder portion which extends from a spiral guide wall of the surface of the tank body is formed on the front end, and a supply port which is capable of being connected with a carbon powder receiver box is arranged on the cylinder portion. A seal mechanism is further covered on the supply port, and a barrier mechanism is sleeved on the cylinder portion and is capable of glidingly moving. The utility model effectively solves the defect and the inconvenience which are produced by a feeder of the carbon powder tank, the supply port and the filling port are implemented a separate structure, the supply port has an opening and closing function using the design of the barrier mechanism, thereby achieving the effects that residual carbon powder does not fell outside the tank body after using, avoiding begriming the machine equipment and polluting the environment, and the assembly is easy.
