Abstract
An image forming apparatus is provided that, even when a recording material is conveyed with a short interval between papers, reduces mistaken detection of a jam without reducing throughput of image formation. To accomplish this, when an interval between papers is not detected by a sensor that is disposed upstream in a conveyance direction but is detected by a sensor that is disposed downstream in the conveyance direction, there is a high possibility of determining that a jam has been generated in which recording material wraps around a fixing roller, but even in such a case, discharge processing is executed normally without a determination that a jam has been generated in which recording material has wrapped around a fixing roller, by using a recording material size and a time period of detection of the interval between papers.
