PROBLEM TO BE SOLVED: To provide a sheet material storage unit capable of regulating a position, in a width direction, of sheet material, while reducing the cost, and to provide a sheet material conveyance device and an image forming apparatus.SOLUTION: A sheet material storage unit includes: a sheet material stack portion 50 where sheet material is stacked; and a pair of first sheet material regulation members disposed so as to be opposed to each other in a sheet material width direction, across the sheet material stacked in the sheet material stack portion, for regulating a position of the sheet material, in the sheet material width direction. The sheet material storage unit has a second sheet material regulation member 54B located at the sheet material side of at least one first sheet regulation member 54A of the pair of first sheet material regulation members, and attached to the first sheet material regulation member so that the distance from the first sheet material regulation member to the sheet material can be changed, for coming in contact with an end surface of the sheet material, in the sheet material width direction, and regulating the position of the sheet material, in the sheet material width direction. At least a dimension of the second sheet material regulation member in a sheet material conveyance direction is less than a dimension of the first sheet material regulation member in the sheet material conveyance direction.SELECTED DRAWING: Figure 1 |
