Claims (2)

像担持体に非接触状態で対向して設けられ、絶縁性の表層を有し、且つ該絶縁層中に該絶縁層の厚みとほぼ同じ粒径の導電粒子を含有させてなる現像剤担持体を有する現像装置であって、
前記現像剤担持体の前記表層の下側には、該表層に沿うように互いに絶縁された多数の電極が設けられ、
前記現像剤担持体の表面に担持されている所定極性に帯電したトナーをホッピングさせるためのホッピング電界を発生させるホッピング電界発生手段を有し、
前記ホッピング電界発生手段は、前記多数の電極に周期的な電圧を印加することにより互いに近接する電極間の電界の向きが周期的に反転するように、前記ホッピング電界を発生させるものであり、
前記現像剤担持体の表面に担持されているトナーを前記像担持体と対向する現像領域へ搬送して該像担持体上の潜像にトナーを付着させることにより該潜像を現像することを特徴とする現像装置。 A developer carrying member provided to face the image carrying member in a non-contact state, having an insulating surface layer, and containing conductive particles having a particle size substantially the same as the thickness of the insulating layer in the insulating layer A developing device comprising:
Below the surface layer of the developer carrier, a number of electrodes insulated from each other along the surface layer are provided,
Hopping electric field generating means for generating a hopping electric field for hopping toner charged to a predetermined polarity carried on the surface of the developer carrying member;
The hopping electric field generating means generates the hopping electric field so that the direction of the electric field between adjacent electrodes is periodically reversed by applying a periodic voltage to the multiple electrodes.
Developing the latent image by transporting the toner carried on the surface of the developer carrying member to a developing area facing the image carrying member and attaching the toner to the latent image on the image carrying member; A developing device . 請求項１に記載の現像装置を備えた画像形成装置。 An image forming apparatus comprising the developing device according to claim 1 .
