To achieve both of the excellent operability and miniaturization.SOLUTION: In an image formation apparatus 1, a tray groove part 35 of a tray 12 in a rear tray part 7 has the curve shape and a stacker groove part 52 of a stacker 13 has the curve shape. In the rear tray part 7, a tray boss 33 is moved along the stacker groove part 52, a stacker boss 51 is moved along a tray groove part 35, the stacker 13 is moved and rotated with respect to the tray 12 and the stacker 13 is shifted between the stored state and the expanded state. In the rear tray part 7, at this time, since a stacker most root portion 13P of the stacker 13 is always located within a range of a stacker storage region RA, there is no need to separately install a region for making the stacker 13 pass therethrough on the root side with respect to the stacker storage region RA in the tray 12, and the length in the conveyance direction of the tray 12 can be suppressed to the minimum level.SELECTED DRAWING: Figure 9 【課題】良好な操作性と小型化とを両立させ得るようにする。【解決手段】画像形成装置１は、リアトレイ部７におけるトレイ１２のトレイ溝部３５を曲線形状とし、且つスタッカ１３のスタッカ溝部５２を曲線形状とした。リアトレイ部７では、トレイボス３３をスタッカ溝部５２に沿って移動させると共に、スタッカボス５１をトレイ溝部３５に沿って移動させることにより、トレイ１２に対してスタッカ１３を移動及び回動させ、該スタッカ１３を収納状態及び展開状態の間で遷移させる。このときリアトレイ部７は、スタッカ１３のスタッカ最根元部分１３Ｐを常にスタッカ収納領域ＲＡの範囲内に位置させるため、トレイ１２においてスタッカ収納領域ＲＡよりも根元側に該スタッカ１３を通過させるための領域を別途設ける必要が無く、当該トレイ１２における搬送方向の長さを最小限に抑えることができる。【選択図】図９
