Sheet binding device and image forming apparatus incorporating same

A sheet binding device for binding together multiple sheets with at least one adhesive toner, the sheet binding device comprising:

• a fusing device configured to fuse an adhesive toner pattern formed in a bonding range of a plurality of sheets based on a bonding strength, the boding strength being determined based on a plurality of variables, the plurality of variables including at least a number of color toners used for forming the adhesive toner pattern, a bonding manner, a number of pixels of the adhesive toner pattern, a toner area ratio of the adhesive toner pattern, and a layer thickness of the adhesive toner pattern;
• and
• a printable range setting unit configured to set a boundary between the bonding range and a printable range in which an image according to image data is formed to prevent the printable range from overlapping the bonding range.
