Claim:
An image forming apparatus comprising: a paper feeding unit which sends out a sheet of paper from a paper feeding tray where the sheet is housed; a transfer unit which transfers a toner image formed on an image holder to the sheet sent out by the paper feeding unit; a carrying unit including a first paper path provided with a plurality of carrying roller pairs each of which is a pair of rollers capable of pressing against each other and being separated from each other, the carrying unit which carries the sheet sent out by the paper feeding unit to the transfer unit with the first paper path; a resistance unit disposed in the carrying unit, and including a resistance roller pair which is a pair of rollers capable of pressing against each other and being separated from each other, the resistance unit which carries the sheet to the transfer unit after stopping the sheet on an upstream side of the transfer unit; a jam detection unit which detects a jam occurring location where a jam occurs; a paper detection unit which detects a sheet location of the sheet being carried; and a control unit which, in response to the jam detection unit detecting that the jam occurring location is outside the resistance unit, (i) sets, in accordance with a size of a remaining sheet which is being carried and is detected by the paper detection unit when the jam occurs, a part of the carrying unit as an accumulation unit where the remaining sheet is accumulated, the part including at least the resistance unit, (ii) releases, among the resistance roller pair and the carrying roller pairs, the rollers of a pair located in the accumulation unit from pressing against each other, and (iii) makes the carrying unit carry the remaining sheet to the accumulation unit.
