Zusammenfassung:	To provide an image forming device reduced in downtime of the device, and control method thereof.SOLUTION: An image forming device has a body part for forming images in a state of tension applied to a continuous medium delivered from a first roller and conveyed to be wound to a second roller, and a tension keeping mechanism for keeping the tension of the continuous medium at the body part when exchanging at least one of the first roller and the second roller. The body part performs preliminary operation for image forming while the tension is kept in operation.SELECTED DRAWING: Figure 1 【課題】装置のダウンタイムを低減可能な画像形成装置及び画像形成装置の制御方法を提供する。【解決手段】画像形成装置は、第１ロールから繰り出されて第２ロールに巻き取られるよう搬送される連続媒体に対して、連続媒体に張力が付与された状態で、画像を形成する本体部と、第１ロール及び第２ロールの少なくとも一方を交換するための操作の際に、本体部における連続媒体の張力を維持する張力維持機構と、を備える。本体部は、操作の際に、張力が保たれている間に画像形成の予備動作を実行する。【選択図】図１
