摘要：
A sheet feeding device includes a sheet accommodating portion for accommodating a sheet stack. A sheet carrying plate carries the sheet stack and has an upstream end supported in the sheet accommodating portion for rotation. A pickup roller contacts an upper face of the sheet stack and dispatches an uppermost sheet. An elevator displaces the sheet carrying plate between a feeding position where the upper face of the sheet stack contacts the pickup roller and a separating position where the upper face of the sheet stack is separated from the pickup roller. A first warm air mechanism blows warm air toward a side of the sheet stack in the sheet accommodating portion, the side being parallel to the sheet feeding direction. A controller controls the elevator so that the sheet carrying plate is displaced between the feeding position and the separating position during a warm air blowing operation.
