Claim:
1. An image forming apparatus comprising: an image forming section configured to form an image on a long sheet of 1000 mm or more; a sheet feeding path including a first sheet feeding path configured to convey a long sheet to the image forming section, and a second sheet feeding path provided continuously with the first sheet feeding path; a jam detection section configured to detect an occurrence of a jam in the sheet feeding path; and a jam clearing section configured to determine whether a unfixed toner image is borne on a long sheet on the sheet feeding path when a jam occurs and whether the long sheet exists across a boundary, to determine a procedure for unjamming in accordance with a determination result, and to make a request to perform unjamming according to a determined procedure, wherein the jam clearing section is configured such that, in a case where an unfixed toner image is borne on a long sheet and the long sheet exists across the boundary when a jam occurs, the jam clearing section makes a request to pull out the first sheet feeding path to perform unjamming after cutting the sheet at a position near the boundary as a cutting position; the image forming apparatus is an electrophotographic image forming apparatus in which unjamming is allowed to be performed by separating the image forming apparatus at the boundary between the first sheet feeding path and the second sheet feeding path, and by pulling out the first sheet feeding path.
