BOOKLET MAKING APPARATUS AND IMAGE FORMING APPARATUS

A booklet making apparatus includes a heat-and-pressure bonding portion including a pressurizing member, a receiving member, a moving portion configured to move the pressurizing member, and a heating portion configured to heat the pressurizing member. 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. The booklet making apparatus further includes an elastic member. A deformation amount of the elastic member is constant while the moving portion moves from a first position to a second position. In a case where the moving portion moves from the second position to a third position, the deformation amount of the elastic member increases in accordance with a movement amount the moving portion.
