<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus which is used without being disturbed even though the deterioration or the like of a sensor is caused without raising the occurring ratio of jamming. <P>SOLUTION: In the image forming apparatus to feed paper from a paper feeding part 21 to a paper delivery part 23 through several sensors 25, 26 and 27, a filler type sensor 25 and a reflection type sensor 26 are arranged in the passing order of the paper, and the apparatus is provided with a jamming detection controlling part 12 for performing control so as to normally deliver the paper without detecting the jamming by the filler type sensor in the case that the reflection sensor 26 is turned on and off when jamming detection time passes after the filler type sensor 25 is turned on. <P>COPYRIGHT: (C)2004,JPO</p> |
