Feeding device and image forming apparatus

A feeding device comprising:

• a feeding device body of which a downstream end portion in a feeding direction, in which a material to be fed is fed, is mounted on a mounting portion, and that is openable and closable between a closed position where an upstream end portion is positioned above the downstream end portion and an open position where the upstream end portion is positioned on a side of the downstream end portion;
• a stacked portion that is provided on the feeding device body and on which the material to be fed is stacked in the open position;
• a detection unit that has a detection member hanging down to a downstream end portion of the stacked portion in the open position, moves to a downstream side in the feeding direction as the detection member is pressed by a downstream end portion of the material to be fed stacked on the stacked portion in the open position, and detects a stack of the materials to be fed on the stacked portion;
• and
• a restriction unit that restricts movement of the detection member to the downstream side in the feeding direction in the closed position,
• wherein the restriction unit includes a contact portion configured to be in contact with the detection member, a weight portion and an intermediate portion between the contact portion and the weight portion, and the intermediate portion is pivotally mounted on the stacked portion.
