The present invention provides an image processing apparatus which can promptly detect whether or not a jam has been removed in the case of occurrence of the jam such as a paper jam. 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. An image processing apparatus 100 includes a position detection portion 41 for detecting a location of a jam which occurs during feeding of recording paper, a determination portion 42 for determining a jam state based on a detection result of the position detection sensor 69, an examination portion 43 for examining whether the jam has been resolved and a resuming portion 44 for resuming the processing when an examination of the jam location by the examination portion 43 is finished. If the position detection sensor 69 detects the occurrence of the jam (S2), the determination portion determines the jam state and simultaneously provides notification of the occurrence of the jam (S4). If clearing work is finished (S5), the examination portion 43 feeds a test sheet (S6). It is detected whether or not the test sheet passes through the jam location (S8), and the processing is resumed if it is detected within predetermined time (S10).
