PRESS-BONDED SHEET MANUFACTURING METHOD, PRESS-BONDED SHEET MANUFACTURING DEVICE, AND IMAGE FORMING DEVICE

WIPO Patent Application WO/2023/054302

A1

Provided is a press-bonded sheet manufacturing method by which a product created by a press-bonding process is peeled smoothly and with the appropriate force, and it is possible to inhibit a drop in adhesive force caused by deformation of the product. This press-bonded sheet manufacturing method, which is for manufacturing a press-bonded sheet in which sheets are press-bonded together in a peelable state, includes: a step for forming an adhesive layer containing a powder adhesive on the sheets; a fixing step for heating the adhesive layer formed on the sheets to fix the adhesive layer to the sheets; a step for causing a region where the adhesive layer on the sheets is formed and fixed to oppose another region where the adhesive layer is formed and fixed on the same sheet or on a different sheet, and superimposing the regions; and a press-bonding step for press-bonding the superimposed locations by pressing under heating. The fracture strain of the main constituent material of the powder adhesive is at least 10% but less than 1000%.
