To provide a recording medium conveyance device and an image formation apparatus which can suppress the abnormal sound that is generated due to the conveyance of a recording medium by a stop roll in comparison to a case where the movement in the axial direction of a first conveyance roll and a second conveyance roll on the upstream side in the conveyance direction of the recording medium is always restrained with respect to the stop roll.SOLUTION: A first conveyance roll forms a loop in a stopped recording medium by bringing the tip of the recording medium into contact with a stop roll, and is movable in the axial direction by receiving the force in the axial direction that is generated in the conveyed recording medium. A second conveyance roll rotates, holds and conveys the recording medium to deliver the recording medium to the first conveyance roll, and is movable in the axial direction by receiving the force in the axial direction that is generated in the conveyed recording medium.SELECTED DRAWING: Figure 1 【課題】停止ロールに対して記録媒体の搬送方向の上流側の第一搬送ロール及び第二搬送ロールの軸方向の移動が常に拘束されている場合と比して、停止ロールが記録媒体を搬送することで生じる異音を抑制することができる記録媒体搬送装置、及び画像形成装置を得る。【解決手段】第一搬送ロールは、停止ロールへ記録媒体の先端を突き当てて停止した記録媒体にループを形成させると共に、搬送している記録媒体に生じる軸方向の力を受けて軸方向に移動可能とされている。第二搬送ロールは、回転して記録媒体を挟んで搬送して第一搬送ロールに記録媒体を受け渡し、搬送している記録媒体に生じる軸方向の力を受けて軸方向に移動可能とされている。【選択図】図１
