Paper feeding device

A paper feeding apparatus arranged along a left-right direction on one side of an image forming apparatus and configured to feed stacked sheets one by one in order from a top sheet to the image forming apparatus from a paper feeding side adjacent to the image forming apparatus, the paper feeding apparatus comprising:

• a base plate;
• a tray on which plural sheets are stacked, the tray being capable of moving up and down with respect to the base plate;
• a front-side guide member arranged on a front side in a front-rear direction orthogonal to a paper feeding direction from the paper feeding side to the image forming apparatus, attached to a front end of the base plate, and extending upward;
• a rear-side guide member arranged on a rear side in the front-rear direction orthogonal to the paper feeding direction, attached to a rear end of the base plate, and extending upward;
• a paper-feeding-side guide member forming an aligning member on the paper feeding side for the stacked sheets, attached to the base plate, and extending upward;
• an opened section formed by opening one side opposite to the paper-feeding-side guide member;
• and
• an auxiliary front guide member arranged between the front-side guide member and the paper-feeding-side guide member and configured to regulate, with an auxiliary guide section, a position on a front end side of the sheets stacked on the tray, the auxiliary front guide member having a sheet guiding section configured to come into contact with a corner on a front side of the paper feeding side of the sheets placed deviating from a proper placing state, and configured to guide the corner to the auxiliary guide section with external force in the paper feeding direction applied to the sheets.
