Press-bonded sheet manufacturing method, press-bonded sheet manufacturing apparatus, and image forming apparatus

A press-bonded sheet manufacturing apparatus for manufacturing a press-bonded sheet in which sheet portions are press-bonded in a peelable state, comprising:

• means for forming an adhesive layer containing powder adhesive on a sheet;
• fixing means for heating the adhesive layer formed on the sheet to fix it to the sheet;
• means for superimposing by opposing an area on the sheet where the adhesive layer is formed and fixed and an area on the same sheet or on a different sheet where another adhesive layer is formed and fixed;
• and
• press-bonding means for pressurizing the superimposed portion of the areas where the adhesive layer has been formed and fixed under heating and press-bonding it,
• wherein a fracture strain of a main constituent material of the powder adhesive is 10% or more and less than 1000%.

An image forming apparatus for manufacturing a press-bonded sheet in which sheet portions are press-bonded in a peelable state, comprising:

• means for forming a toner image on a sheet using printing toner;
• means for forming an adhesive layer containing powder adhesive on the sheet;
• fixing means for heating the toner image and the adhesive layer formed on the sheet to fix them to the sheet;
• means for superimposing by opposing an area on the sheet where the adhesive layer is formed and fixed and an area on the same sheet or on a different sheet where another adhesive layer is formed and fixed;
• and
• press-bonding means for pressurizing the superimposed portion of the areas where the adhesive layer has been formed and fixed under heating and press-bonding it,
• wherein a fracture strain of a main constituent material of the powder adhesive is 10% or more and less than 1000%.
