PROBLEM TO BE SOLVED: To provide a sheet storage cassette in which even if an excessive force is exerted on an upper-surface cover in an opening direction, the upper-surface cover is hard to come off, and an image forming apparatus having the same.SOLUTION: The sheet storage cassette includes a cassette base and a cover member. The cover member is supported swingably on a first rotation fulcrum and a second rotation fulcrum at both side surfaces of the cassette base, the first rotation fulcrum being composed of a first engagement hole formed in either one of the cover member and the cassette base and a first boss portion formed in the other one of the cover member and the cassette base to engage with the first engagement hole, and the second rotation fulcrum being composed of a second engagement hole formed in either one of the cover member and the cassette base and a second boss portion formed in the other one of the cover member and the cassette base to engage with the second engagement hole. A distance from a tip end of the second boss portion to an engagement position of the second engagement hole is smaller than a distance from a tip end of the first boss portion to an engagement position of the first engagement hole, and a swing limiting part, which limits an open angle of the cover member, is disposed only at the side of the first rotation fulcrum.SELECTED DRAWING: Figure 12 |
