PURPOSE:To simplify a feeding means of developing material to a guide member by providing a vibrating member whose one end part is opposed to the guide member of the developing material, and another end is fixed to a vessel of the developing material, and constituting so that this vibrating member is made to vibrate. CONSTITUTION:By rotating motion of a magnet member 20, alternating magnetic field is generated in its vicinity. A vibrating member 6, especially its magnetic material part 9 is positioned under the influence of its magnetic field, therefore, the vibrating member 6 is vibrated by synchronizing with a rotation of the magnet 20. In this case, a developing material stored in bridge-shape vicinity of a funnel-shaped outlet 8 of a vessel breaks down its bridged state due to a vibration of the vibrating member 6. The developing material 7 is carried to a direction of a sleeve 4, vibrating on an inclined surface 6-1 of the vibrating member 6. In that case, a comparatively large toner particle collected body which has been coagulated naturally is also pulverized to pieces by the vibration, and a fine toner particle is supplied to the sleeve 4. In this way, a feeding means of the developing material to a guide member is simplified. |
