IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD

To secure durability of an intermediate transfer body together with transferability of an image by efficiently heating the intermediate transfer body.SOLUTION: A heating part 10 heats an intermediate transfer body 2 by using a plurality of heating sources that are positioned by being displaced in a direction of rotation of the intermediate transfer body 2. The plurality of heating sources include a first heating source for heating an intermediate transfer body 1, and a second heating source that is positioned at an upstream side in the direction of rotation of the intermediate transfer body 2 and that heats the intermediate transfer body 1 at a degree higher than a degree at which the first heating source heats the intermediate transfer body 1.SELECTED DRAWING: Figure 1 【課題】中間転写体を効率よく加熱して、画像の転写性と共に中間転写体の耐久性を確保する。【解決手段】加熱部１０は、中間転写体２の回転方向にずれて位置する複数の加熱源を用いて中間転写体２を加熱する。複数の加熱源は、中間転写体１を加熱する第１の加熱源と、第１の加熱源よりも中間転写体２の回転方向の上流側に位置して、第１の加熱源が前記中間転写体１を加熱する程度よりも高い程度で前記中間転写体１を加熱する第２の加熱源と、を含む。【選択図】図１
