PROBLEM TO BE SOLVED: To prevent, in a toner storage device having a rotor for stirring or carrying toner in a toner container, a toner leak from the part to which a rotary hold member (stir shaft) holding the rotor rotatably is attached. SOLUTION: As toner seals for the part to which the stirring shaft is attached, two oil seals 26 and 27 of different diameters are used, and the oil seal 27 with a large diameter is disposed outside the other. Also, the stirring shaft 10 has shaft parts of different outside-diameters which engage with the two oil seals 26 and 27, and a level difference part 10b exists between them. |
