PROBLEM TO BE SOLVED: To prevent toner from dispersing when a toner cartridge is removed and to improve operability of the toner cartridge. SOLUTION: With regard to a toner cartridge equipped with an agitating blade 23, which is rotatable inside a round cylinder including an opening 21a in the thrust direction, the agitating blade 23 is composed of a main blade 23a approximately parallel to its opening 21a and a sub-blade 23b approximately vertical to the opening 21a, while the sub-blade 23b contacts internally with the round cylinder inside diameter in a circular arc approximately conforming to the round cylinder inside diameter and the agitating blade never protrudes beyond the opening 21a by extending the circular arc length longer than that of the opening arc. |
