摘要： The present invention provides a sheet feeding apparatus including an overlapped feeding detection apparatus which can securely detect overlapped feeding as to a sheet being fed, and a document feeding apparatus and an image processing apparatus including the sheet feeding apparatus. A paper feeding apparatus 1b includes a paper feed tray 11, a pickup roller 61, a paper roller 63, a sorting roller 64, feeding rollers 66a, resist rollers 67, a paper ejection roller 73, a passage detection sensor 69, an overlapped feeding detection sensor 68 and a second detection apparatus 71. Recording paper is delivered from the paper feed tray 11 by the pickup roller 61 according to a printing instruction from a user. The recording paper is fed to the resist rollers 67 through the paper roller 63, the sorting roller 64, the feeding rollers 66a and the passage detection sensor 69. The recording paper temporarily stops at the resist rollers 67. In this case, the overlapped feeding detection sensor 68 detects overlapped feeding of the recording paper.
