主权项

1. A paper feeding cassette loadable into and unloadable from an image forming apparatus body, said paper feeding cassette comprising:
a tray housing stacked paper media and having a bottom of an approximately rectangular shape and a sidewall provided to surround the bottom; and a trailing edge regulating member slidably disposed in a guide region placed in said bottom so as to extend along a paper feeding direction in which said paper media are fed and regulating a position of a trailing edge of said paper media in said paper feeding direction, said trailing edge regulating member including a base portion and an upright wall provided in said base portion on a rear side in said paper feeding direction, said sidewall including a rear sidewall provided on a trailing edge side of said paper media in said paper feeding direction, said upright wall including a first upright portion fixedly attached to said base portion and extending upright from said base portion, and a second upright portion provided directly above said first upright portion and having a rear end face located rearwardly of a rear end face of said first upright portion, and wherein said second upright portion includes a first elastic portion for that regulates movement of said trailing edge regulating member in said paper feeding direction by applying elastic force in a direction orthogonal to said paper feeding direction, and when said trailing edge regulating member is located on a rearmost side in said guide region, the rear end face of said first upright portion is brought into contact with an inner face of said rear sidewall and a least a part of the first elastic portion is located directly above said rear sidewall, and a thickness, in the paper feeding direction, of the second upright portion is thicker than the thickness of the first upright portion, and the thickness, in the paper feeding direction, of the first elastic portion of the second upright portion is substantially the same as the thickness of the second upright portion.
