Abstract

PURPOSE: To perform always stable development by providing an auxiliary plate for preventing toner effluence near the effluent port of a toner hopper.
CONSTITUTION: An auxiliary plate 7 is disposed near the effluent port of the magnetic toner 4 of a tone hopper 6 in such a manner that its one end a is in proximate to a magnetic toner flow defining plate 8 with its spacing from a non-magnetic sleeve 1 being made equal to the spacing between the defining plate 8 and non-magnetic sleeve 1 and that the other end 7(b) is placed closer to the non-magnetic sleeve 1 than the one end 7(a). As a result of this, the magnetic toner 4 on the auxiliary plate 7 is conveyed in the counter X direction by the X-direction rotation of the magnet roll 2, whereby the toner pool 5' is formed and maintained. Even if the magnetic toner 4 is conveyed in the X direction between the auxiliary plate 1 and non-magnetic sleeve 1, it is conveyed in the counter X direction from the other end 7 (b)on the auxiliary plate 7, whereby the formation of the toner pool on the non-magnetic sleeve 1 is obviated. Hence, the toner supply onto the non-magnetic sleeve 1 stabilizes and the intended object achieved.
