    摘要： A developing apparatus includes a developer containing portion containing a developer having a weight average particle diameter of not more than 7 &mgr;m, a developer bearing member for bearing a developer, and an agitating member that agitates the developer contained in the developer containing portion. The agitating member is intermittently driven with respect to rotation of a developing sleeve. The agitating member is driven to rotate for one page every time the image forming apparatus performs a predetermined number of printing operations. A rod member having a crank-like shape may be used as the agitating member and both of the end portions serve as the center of rotation. By controlling the drive of the agitating member, it is possible to effectively adjust the supply of toner to the developing sleeve and prevent the density lowering phenomena caused due to inflow of a large amount of the new toner presented at the rear of the developing container. The agitating member may be positioned closest to the developing sleeve and may be arranged below the toner container. Accordingly, to these arrangements, the image density after printing a low print pattern can be prevented from being lessened to obtain a uniform image density even though a one-component magnetic developer having the weight average particle sized diameter of not more than 7 &mgr;m is used.

    摘要翻译： 显影装置包括含有重均粒径不大于7μm的显影剂的显影剂容纳部分，用于承载显影剂的显影剂承载部件和搅拌包含在显影剂容纳部分中的显影剂的搅拌部件。 搅拌构件相对于显影套筒的旋转间歇地驱动。 每当图像形成装置执行预定数量的打印操作时，搅拌构件被驱动旋转一页。 可以使用具有曲柄形状的杆构件作为搅拌构件，并且两个端部用作旋转中心。 通过控制搅拌构件的驱动，可以有效地调节向显影套筒的调色剂供应，并且防止由于大量新鲜调色剂流入显影容器的后部而引起的浓度降低现象。 搅拌构件可以定位成最靠近显影套筒并且可以布置在调色剂容器的下方。 因此，对于这些布置，即使使用重均粒径不大于7μm的单组分磁性显影剂，也可以防止印刷低印刷图案之后的图像浓度，以获得均匀的图像浓度 。
