面間隔で近接対向した現像スリーブとが共通の回
転軸を中心にそれぞれ回動自在に、且つ前記現像
スリーブが現像剤と接触するようにケース内に配
され、前記マグローラと前記現像スリーブとは、
駆動手段によつて所定の回転速度比で回転され、
この回転によつて前記現像剤が前記マグローラが
形成する磁界により、前記現像スリーブの周面に
付着して感光体表面に搬送され、顕画像を前記感
光体表面に形成する電子画像形成機の現像装置に
おいて、前記ケースを本体から取り外して行なう
前記現像剤の交換補充時に、前記マグローラと前
記現像スリーブとを、ほぼ前記所定の回転速度比
で回転させる補充駆動手段を設けたことを特徴と
する電子画像形成機の現像装置。 A mag roller and a developing sleeve that closely opposes the outside of the mag roller at a predetermined circumferential distance are arranged in a case so as to be rotatable about a common rotation axis, and so that the developing sleeve comes into contact with the developer. , the mag roller and the developing sleeve are:
rotated by a driving means at a predetermined rotational speed ratio;
As a result of this rotation, the developer adheres to the circumferential surface of the developing sleeve and is conveyed to the surface of the photoreceptor by the magnetic field formed by the mag roller, and is used in an electronic image forming machine that forms a visible image on the surface of the photoreceptor. The apparatus is characterized in that a replenishment driving means is provided for rotating the mag roller and the developing sleeve at approximately the predetermined rotational speed ratio when the developer is replaced and replenished by removing the case from the main body. Developing device of image forming machine.
