Booklet making apparatus and image forming apparatus

A booklet making apparatus comprising:

• a heat-and-pressure bonding portion configured to heat and pressurize a sheet, the heat-and-pressure bonding portion including:
• a pressurizing member configured to come into contact with and pressurize the sheet,
• a receiving member configured to oppose the pressurizing member,
• a moving portion configured to move the pressurizing member such that the pressurizing member and the receiving member nip and pressurize the sheet, and
• a heating portion configured to heat the pressurizing member,
• wherein the booklet making apparatus is configured to nip, heat, and pressurize, between the pressurizing member and the receiving member, a plurality of sheets on at least one of which an adhesive layer is formed, and thus make a booklet in which the plurality of sheets are bonded to each other via the adhesive layer,
• wherein the booklet making apparatus further comprises:
• an elastic member configured to generate an urging force for applying a pressure between the pressurizing member and the receiving member;
• a drive source configured to drive the moving portion;
• a detection portion configured to detect contact of the pressurizing member with the plurality of sheets;
• and
• a controller configured to control a driving amount of the drive source on a basis of a detection result of the detection portion,
• wherein the controller is configured to adjust a driving amount of the drive source between (i) detection of contact of the pressurizing member with the plurality of sheets by the detection portion and (ii) stoppage of the drive source,
• wherein the heat-and-pressure bonding portion includes a pressurizing unit that includes the pressurizing member and that is configured to be moved by the moving portion,
• wherein the elastic member is provided between the pressurizing unit and the moving portion, and
• wherein the detection portion is configured to detect change in a positional relationship between the pressurizing unit and the moving portion.
