Image forming apparatus

An image forming apparatus comprising:

• an image forming unit that forms an image on a sheet;
• a fixing unit that fixes the image formed on the sheet to the sheet;
• a belt unit that conveys a sheet along the image forming unit to the fixing unit in a sheet conveying direction;
• a first sheet discharging path, which discharges a sheet passed through the image forming unit, and which has a first dischargeable minimum sheet length;
• a second sheet discharging path, which discharges the sheet passed through the image forming unit, and which has a second dischargeable minimum sheet length, the second dischargeable minimum sheet length being shorter than the first dischargeable minimum sheet length;
• a measuring unit that measures a length of the sheet conveyed to the image forming unit;
• and
• a control unit that is connected to the image forming unit, the fixing unit, the belt unit, the first sheet discharging path, the second sheet discharging path and a measuring unit;
• wherein, when the length of the sheet measured by the measuring unit is shorter than the first dischargeable minimum sheet length in a state in which the first sheet discharging path is selected, the control unit is configured to:
• control the image forming unit to form the image on the measured sheet;
• control the belt unit to convey the measured sheet downstream in the sheet conveying direction from the image forming unit;
• and
• control the belt unit to stop conveyance of a sheet subsequent to the measured sheet at a position upstream in the sheet conveying direction from the measured sheet.
