To provide a paper feeding device capable of suppressing contact of a sheet with a part other than a paper feeding roller even when the sheet to be fed is corrugated.SOLUTION: A paper feeding device 3 comprises: a paper feeding tray 10; a paper feeding roller 32; and a sheet loading device 11 which can be lifted and lowered between a first position for enabling paper feeding of a sheet S with the paper feeding roller 32 and a second position, lower than the first position, for loading the sheet S, and has a first loading plate 12 having a first loading surface 121 supporting the sheet S and a second loading plate 13 having a second loading surface 131 supporting the sheet S and arranged lower than the first loading plate 12 when the sheet loading device 11 is positioned at the second position. The first loading plate 12 has a notch part 123 at a position facing the paper feeding roller 32 in a front end. In a state where the sheet loading device 11 is positioned at the first position, the second loading surface 131 is protruded from the notch part 123 and positioned upper than the first loading surface 121.SELECTED DRAWING: Figure 6 【課題】給紙されるシートに波打ちが生じても、シートが給紙ローラ以外の部分に接触することを抑制できる給紙装置を提供する。【解決手段】給紙装置３は、給紙トレイ１０と、給紙ローラ３２と、給紙ローラ３２によるシートＳの給紙を可能にする第１位置と、第１位置よりも下方でシートＳを積載する第２位置との間で昇降可能なシート積載装置１１であって、シートＳを支持する第１積載面１２１を有する第１積載板１２と、シートＳを支持する第２積載面１３１を有し、シート積載装置１１が第２位置に位置するときに第１積載板１２よりも下方に配置される第２積載板１３とを有するシート積載装置１１とを備え、第１積載板１２は、前端における給紙ローラ３２と対向する位置に切り欠き部１２３を有し、シート積載装置１１が第１位置に位置した状態で、第２積載面１３１は切り欠き部１２３から突出して第１積載面１２１よりも上方に位置する。【選択図】図６
