Patent ID: 7568510

Claim:
A bookbinding apparatus that is connectable to an image forming apparatus and carries out bookbinding by bonding a plurality of sheets outputted from the image forming apparatus using an adhesive, the bookbinding apparatus comprising: a filter that prevents volatile components of the adhesive from leaking out to the surroundings; a heating device that heats the adhesive; a detecting device that detects a temperature of the adhesive; an adhesive temperature controller that controls a heating temperature of the adhesive by said heating device, based on the temperature of the adhesive detected by said detecting device and a target temperature; and a filter exchange time determining device that determines whether or not said filter has reached an exchange time thereof, wherein said adhesive temperature controller is operable when said filter exchange time determining device determines that said filter has reached the exchange time thereof, to control the heating temperature of the adhesive by said heating device so that the temperature of the adhesive becomes lower than a predetermined temperature that is lower than the target temperature.
