ABSTRACT:
An image forming apparatus according to the invention includes a first sheet-transfer unit for transferring a sheet, a second sheet-transfer unit for transferring downstream the sheet transferred from the first sheet-transfer unit, and a pivotable member for supporting either the first sheet-transfer unit or the second sheet-transfer unit. When an abnormal transfer state of a sheet is detected in the image forming apparatus, a controller controls driving at least one of the first sheet-transfer unit and the second sheet-transfer unit so as to move the sheet which stops spanning the first and second sheet-transfer units by a predetermined amount of movement, thereby forming a loop in the sheet.
