Paper feed cassette, paper feeding device, and image formation device

In the present invention, a paper feed cassette is provided with an end cursor, a pair of gears, and a pair of racks. The end cursor regulates the position of a paper-feed-direction rear end part of accommodated paper. The end cursor can be slid in a conveyance direction. The pair of gears are rotatably provided to a lower surface of a base part of the end cursor. The pair of gears have the same number of modules and teeth. The pair of racks are provided in parallel to one another along the direction of sliding of the end cursor, on a bottom surface of a cassette body. The pair of racks are engaged with the pair of gears. This makes it possible to prevent paper from experiencing problems such as skewing, edge-folding, or wrinkling, and enables the end cursor to be slid with good operability and smoothly.
