PURPOSE: To prevent print a density dispersion in a direction of the width of a printing medium from being generated. CONSTITUTION: The device is equipped with a stirring bar 25, which is freely rotatably supported in a toner storage tank and also supports a circulation spiral 35 freely rotatably, a first rotation transmission means, which transmits rotation from a driving source to the stirring bar 25, and a second rotation transmission means, which transmits rotation from the first rotation transmission means to the circulation spiral 35. Because the stirring bar 25 is rotated in the toner storage tank, toner can be stirred in the direction in which the printing medium is carried. The circulation spiral 35 rotates while rotating around the rotary shaft of the stirring bar 25, and it rotates an auger, therefore the toner can be stirred in the direction of the width of the printing medium. |
