Image forming system

An image forming system, comprising:

• A sheet processing apparatus configured to separate a two-ply sheet in which two sheets are overlaid and bonded together at a portion of the two-ply sheet, and sandwich a sheet medium between the sheets of the two-ply sheet;
• A heat presser configured to heat and press the two-ply sheet;
• An image forming apparatus configured to form an image on the sheet medium;
• And
• Control circuitry configured to perform:
• A first mode to cause the sheet processing apparatus to sandwich the sheet medium, on which an image has been formed by the image forming apparatus, between the two sheets of the two-ply sheet and cause the heat presser to laminate the two-ply sheet;
• and
• A second mode to cause the heat presser to laminate a sheet set that includes the sheet medium sandwiched between the two sheets of the two-ply sheet by a user,
• Wherein the control circuitry is configured to switch between the first mode and the second mode based on input from the user,
• Wherein, in the first mode, the control circuitry is configured to form the image on the sheet medium using the image forming apparatus, and
• Where, in the second mode, the image forming system does not operate the image forming apparatus and the control circuitry does not form the image on the sheet medium using the image forming apparatus.
