Image forming apparatus

An image forming apparatus comprising:

• a printing unit configured to print an image on a sheet, the printing unit including a fixing unit configured to fix the image onto the sheet with heat;
• a first conveyance path through which the sheet on which the image is printed by the printing unit is conveyed;
• a first stacking unit on which the sheet conveyed through the first conveyance path is stacked;
• a second conveyance path through which the sheet on which the image is printed by the printing unit is conveyed;
• a second stacking unit on which the sheet conveyed through the second conveyance path is stacked;
• and
• a control unit configured to control the printing unit,
• wherein, in a case where the control unit controls the printing unit to execute a printing operation, the printing unit continuously forms the image on a plurality of sheets and then suspend the printing operation,
• wherein the control unit controls the printing unit such that (i) a period from a time when the printing operation is started to a time when the printing operation is suspended in a case where the sheet is caused to pass through the first conveyance path and is conveyed to the first stacking unit is different from (ii) a period from a time when the printing operation is started to a time when the printing operation is suspended in a case where the sheet is caused to pass through the second conveyance path and is conveyed to the second stacking unit.
