PROBLEM TO BE SOLVED: To stably store, replenish, and highly-accurately position a long paper without significantly changing a present tray structure.SOLUTION: A paper feeder includes: a plurality of slide rails mounted on the paper feeder; a box-shaped drawer unit which can move to an image forming means side on the slide rails; a slide unit and an extension tray which are arranged on a front of and a back of the drawer unit in a moving direction; a slide bottom plate which can be lifted by loading means and can slide horizontally on the drawer unit; tip end paper positioning means which rises when the slide bottom plate is drawn out horizontally and falls when the slide bottom plate is pushed in horizontally; and connecting means which is connected to a handle for drawing the drawer unit horizontally when the slide bottom plate is positioned at a lowest point. 【課題】現状のトレイ構成を大きく変えることなく長尺用紙を安定して保管し、補給し、精度良く位置決めできること。【解決手段】給紙装置に取り付けられる複数のスライドレールと、スライドレール上を画像形成手段側に移動可能な箱形の引き出しユニットと、引き出しユニットの移動方向の前後に設けられたスライドユニット及び延長トレイと、積載手段により昇降可能、かつ引き出しユニットの上に水平方向にスライド可能なスライド底板と、スライド底板を水平方向に引き出すと起き上がり、水平方向に押し入れると倒れる先端用紙位置決め手段と、スライド底板が最下点に位置したときに引き出しユニットを水平方向に引き出す取手と連結する連結手段と、を備えた。【選択図】図１５
