A bookbinding quality is improved by preventing an ink of a letter printed on sheets from being blurred in a process of heat-fixing a tape to a sheet bundle and reliably performing a heat-fixing operation, with a simple structure. A bookbinding device includes: a heater unit which applies a predetermined heat to a bookbinding tape by a heater so that a binding portion of a sheet bundle is pressure-bonded by melting an adhesive adhered to one surface of the bookbinding tape; a heater moving unit which moves the heater; a sheet bundle moving unit which moves the sheet bundle in a nipped state; and a control unit which controls the heater moving unit and the sheet bundle moving unit so as to perform a preliminary heating step in which the binding portion of the sheet bundle is heated by the heater in advance and a heat-fixing step in which a bookbinding tape is heat-fixed to the binding portion of the sheet bundle by the heater while the bookbinding tape overlaps the binding portion of the heated sheet bundle. |
