Abstract

PURPOSE:To stir a developer with high efficiency by forming an opening extending over a range containing a spiral stirring plate provided at every interval in the peripheral direction, omitting only a spiral stirring blade part of a part corresponding to the opening, and providing the spiral stirring blade extending over almost the whole of the peripheral surface part of a cylinder. CONSTITUTION:By cutting a spiral stirring blade part of a part corresponding to an opening 16, it does not occur that a developer is pushed aside to the peripheral surface part by the spiral stirring blade part concerned, and also, the opening 16 formed in a cylinder 12 is large in the peripheral direction, and a developer is scooped in satisfactorily by a opening edge part (e) by following up a rotation of a developer stirring roller 4. Accordingly, the developer positioned in the vicinity of the opening 16 is led efficiently into the inside of the cylinder, and the contained quantity of the developer to the inside of the cylinder 12 increases. As a result, the stirring efficiency of the developer becomes high. Also, since the spiral stirring blade 13 is provided on almost the whole of the peripheral surface part of the cylinder 12, the efficiency of rotational stirring of the developer by the developer stirring roller 4 is satisfactorily maintained.
