Zusammenfassung: | To provide an intermediate transfer unit capable of improving transferability by suppressing scattering of toner, while securing the stability of the intermediate transfer unit, when a vibration application member is provided in a holding roller, in the transfer nip part of the intermediate transfer unit and to provide an image forming apparatus.SOLUTION: An intermediate transfer unit 20 includes a toner image carrier 21 which carries a toner image, a holding roller 24 which holds the toner image carrier 21, a transfer roller 33 which forms a nip part N together with the holding roller 24 through the toner image carrier 21, and a vibration application member 44 which is arranged in contact with the surface of the holding roller 24 and applies a vibration to the holding roller 24.SELECTED DRAWING: Figure 1
【課題】中間転写ユニットのニップ部において、保持ローラーに振動付与部材を設けた場合に、中間転写ユニットの安定性を確保しつつ、トナーの飛び散りを抑制して、転写性の向上を可能とする中間転写ユニットおよび画像形成装置を提供することを目的とする。【解決手段】この中間転写ユニット20は、トナー像を担持するトナー像担持体21と、トナー像担持体21を保持する保持ローラー24と、トナー像担持体21を介して保持ローラー24とニップ部Nを形成する転写ローラー33と、保持ローラー24の表面に接触して配置され、保持ローラー24に振動を付与する振動付与部材44とを備える。【選択図】図1 |
