1. A sheet processing device configured to sandwich a sheet-shaped medium in a two-ply sheet in which two sheets are overlaid and partially bonded, the sheet processing device comprising:
a heat presser configured to heat and press the two-ply sheet in which the sheet-shaped medium is sandwiched;
a heat-pressing conveyance path on which the heat presser is disposed;
a non-heat-pressing conveyance path on which the heat presser is not disposed;
a brancher configured to branch the two-ply sheet into the heat-pressing conveyance path or the non-heat-pressing conveyance path; and
a stacker configured to stack both a heat-pressed sheet and a non-heat-pressed sheet,
the heat-pressed sheet being the two-ply sheet heated and pressed by the heat presser and ejected from the heat-pressing conveyance path,
the non-heat-pressed sheet being the two-ply sheet ejected from the non-heat-pressing conveyance path without being heated and pressed through the non-heat-pressing conveyance path.
