Abstract
A paper feeding device has a paper feed tray, a device body, a fan, a rectifying member, and a retreat mechanism. A paper bundle in which a plurality of sheets of paper are stacked can be placed on the paper feed tray. The rectifying member is positioned above the paper bundle placed on the paper feed tray in a state in which the paper feed tray is accommodated in an accommodating part of the device body. The rectifying member generates a negative pressure between the rectifying member and an uppermost sheet of paper of the paper bundle using airflow from the fan in a state in which the paper feed tray is accommodated in the accommodating part. The retreat mechanism displaces the rectifying member in conjunction with the paper feed tray so that the rectifying member retreats from the paper feed tray in at least one of a pull-out operation and a push-in operation of the paper feed tray.
