To prevent a decrease in print quality by eliminating a blocking phenomenon caused in a non-adhesion area by diffusion of heat during heat-adhesion using toner.
There is provided a staple device which binds a sheet bundle by re-fusing toner on a sheet P by heating heaters 301, 302. The staple device includes a plurality of perforating blades 210 which form arrays of perforations Ph, stopping propagation of heat between a toner pattern Pc for adhesion for bonding sheets to each other, and a character/image information part In which includes character and image information and is set as a non-adhesion area at the border between both of the regions. The perforating blades move down to a plurality of sheets which are stacked to form the perforations Ph at a time, and air layers in the perforations Ph stop propagation of heat.
