PROBLEM TO BE SOLVED: To provide a toner cartridge which does not allow easy filling with toner when recycling the toner cartridge. SOLUTION: A collar 10 which is attached to an agitator shaft 1a has the shape of a flange. The radius of it is made longer than a distance between the center of the agitator shaft 1a and the toner filling port 6 of a lower case 5. A hole 10a is made in the radial part of the collar which coincides with the toner filling port 6 of the lower case 5. When the agitator shaft 1a is rotated and the hole 10a of the collar 10 is not in the same position as the filling port 6, filling with toner is inhibited even after the removal of a cap attached to the toner filling port 6. |
