| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a developing device that can suppress a toner from scattering from a gap formed between the surface of a developer carrier and the surface of a recovery rotor.SOLUTION: A recovery roller 13 and a developing sleeve 8 are set to rotate in the same direction at a part in proximity to each other such that a take-in magnetic pole S2 of a magnet roller 8a brings the tips Tb1 of magnetic bristles Tb formed of a developer T carried on the surface of the developing sleeve 8 into contact with the surface of the recovery roller 13.SELECTED DRAWING: Figure 5
【課題】 本発明は、現像剤担持体の表面と、回収回転体の表面との間に形成されるギャップからトナーが飛散することを抑制出来る現像装置を提供する。【解決手段】 回収ローラ13と、現像スリーブ８とは、その近接部において同方向に回転し、マグネットローラ８ａの取り込み磁極Ｓ２によって現像スリーブ８の表面に担持された現像剤Ｔからなる磁気穂Ｔｂの先端Ｔｂ１が、回収ローラ13の表面に接触するように設定されたことを特徴とする。【選択図】 図５ |
