IMAGE FORMATION METHOD AND IMAGE FORMATION APPARATUS

To provide an image formation method and an image formation apparatus with excellent cleaning effect of an image formation surface of an intermediate transfer body, and which maintains the excellent image quality by preventing damage on image formation surface even when cleaning is repeatedly executed.SOLUTION: An image formation method comprises: an intermediate image formation step of forming an intermediate image by applying ink to an image formation surface of an intermediate transfer body; a transfer step of transferring the intermediate image to a recording medium; and a cleaning step of cleaning the image formation surface by bringing a cleaning member into contact with the image formation surface of the intermediate transfer body. The storage elastic modulus E of a material constituting the image formation surface of the intermediate transfer body is 10-100 MPa. The dynamic friction coefficient between the image formation surface and the cleaning member is 0.1-2.0.SELECTED DRAWING: Figure 1 【課題】中間転写体の画像形成面の清掃効果が高く、かつ、清掃を繰り返し実施しても、画像形成面が損傷しにくいため、画像の画質が良好な状態を保持する。【解決手段】中間転写体の画像形成面にインクを付与して中間画像を形成する中間画像形成工程と、該中間画像を記録媒体に転写する転写工程と、該中間転写体の画像形成面に清掃部材を当接させて該画像形成面を清掃する清掃工程と、を有する画像形成方法において、該中間転写体の画像形成面を構成する材料の貯蔵弾性率Ｅが１０～１００ＭＰａ、該画像形成面と該清掃部材との動摩擦係数が０．１～２．０であることを特徴とする画像形成方法。【選択図】図１
