Image forming apparatus and image formation system

An image formation system comprising:

• a sheet feeding apparatus configured to feed a long sheet;
• an image forming apparatus configured to form an image on the long sheet fed from the sheet feeding apparatus, the image forming apparatus including:
• an image forming section configured to form a toner image on the long sheet at an image formation position,
• a first conveyance section disposed on an upstream side of the image formation position in a sheet conveyance direction of the long sheet, and configured to convey the long sheet to the image formation position,
• a second conveyance section disposed on a downstream side of the image formation position in the sheet conveyance direction, and configured to convey the long sheet on which the toner image is formed,
• a displacement detection section configured to detect displacement of the long sheet in a sheet width direction which is perpendicular to the sheet conveyance direction, and
• a control section configured to move the first conveyance section in the sheet width direction to orient the long sheet in the sheet width direction, and move the second conveyance section in a direction identical to a direction along which the first conveyance section is moved based on a detection result of the displacement detection section;
• and
• a winding apparatus configured to wind up the long sheet on which an image is formed by the image forming apparatus.
