PURPOSE:To efficiently agitate a pulverulent developer and simplify the titled device by mounting many deflecting guide plates for deflecting and moving the pulverulent developer advancing along a brade in the axial direction of a developer holding member. CONSTITUTION:Many deflecting guide paltes 8 for deflecting and moving tonor stopped from advancing by a brade 5 in the axial direction of a tonor holding member are fitted to the tonor stopping surface of the brade 5. The tonor 2 stopped from advancing by the brade 5 is stayed just prior to the brade 5, pushed by the succeeding tonor and then deflected in the axial direction of a sleeve 3 by the deflecting guide plates 8 while being moved in the upper direction along the surface of the brade 5. By the deflecting movement, the tonor 2 is agitated naturally and sufficiently. Since it is unnecessary to mount a specific moving agitation member for moving the tonor in axial direction of the sleeve, the developer is simplified. |
