To provide a sheet feeding device and image formation apparatus which can properly adjust the air capacity of the air.SOLUTION: A sheet feeding device comprises: air spray means which floats a sheet on the upper part of a sheet bundle by spraying the air to the sheet bundle loaded on a sheet loading part; feeding means which feeds the floating uppermost sheet; imaging means which images the sheet floated by the air spray means; and air capacity adjustment means which adjusts the air capacity of the air on the basis of the image obtained by the imaging means. The air capacity adjustment means makes the spray states of the air mutually different from each other to adjust the air capacity of the air on the basis of the plurality of images obtained by the imaging means in each spray state.SELECTED DRAWING: Figure 14 【課題】エアの風量を適切に調整することができるシート給送装置および画像形成装置を提供する。【解決手段】シート積載部に積載されたシート束に対してエアを吹き付けてシート束の上部のシートを浮上させるエア吹き付け手段と、浮上した最上位シートを給送する給送手段と、エア吹き付け手段により浮上したシートを撮影する撮像手段と、撮像手段が撮影した画像に基づいて、エアの風量を調整する風量調整手段とを備えたシート給送装置において、風量調整手段は、エアの吹き出し状態を互いに異ならせ、各吹き付け状態で撮像手段により撮影した複数の画像に基づいて、エアの風量を調整する。【選択図】図１４
