In a construction wherein at the start of fixing, a pressure belt is brought into contact with a fixing roller at uniform timing, it has sometimes been the case that the temperature of the pressure belt at a point of time whereat the fixing is started does not become a desired temperature but faulty fixing occurs. The timing for bringing the pressure belt into contact with the fixing roller at the start of fixing is changed in accordance with the detected temperature of the pressure belt. By such a construction, faulty fixing can be prevented from occurring.

A bookbinding apparatus which is capable of suppressing volatile components of an adhesive causing abnormal odor from leaking out of the bookbinding apparatus, to thereby reduce discomfort to nearby operators and an operator exchanging a deodorizing filter. The bookbinding apparatusis connectable to an image forming apparatusand carries out bookbinding by bonding a plurality of sheets outputted from the image forming apparatuswith the adhesive. An adhesive heaterheats the adhesiveand a temperature sensordetects a temperature of the adhesive. An adhesive temperature controllercontrols a heating temperature of the adhesiveby the adhesive heater, based on the temperature of the adhesivedetected by the temperature sensorand a target temperature. When the adhesive temperature controllerreceives an instruction from the image forming apparatusto set the temperature of the adhesiveto a predetermined temperature that is lower than the target temperature, the adhesive temperature controllercontrols the heating temperature of the adhesiveby the heating device, so that the temperature of the adhesivebecomes lower than a predetermined temperature that is lower than the target temperature.

In an image forming apparatus including a fixing device that uses a pressure belt as at least one of two pressing members, a warm-up time and time for shifting to a standby state are reduced with simple control without increasing power consumption. The two pressing members are brought into a press-contact state by a contacting/separating mechanism and only heating means on the upper side is turned on. When the temperature of the upper pressing member increases to temperature near a target temperature corresponding thereto, the pressing members are driven to rotate. When it is detected by temperature detecting means on the lower side that the temperature of the lower pressing member increases to temperature near a target temperature corresponding thereto, the two pressing members are brought into a separated state by the contacting/separating mechanism.

An image forming apparatus has an image forming device for forming an image on a recording material; a heating member heating the image formed on the recording material in a nip portion; an endless belt conveying the recording material toward the nip portion formed between itself and the heating member; a contacting and separating device for bringing the heating member and the belt into the contact with each other and for separating the heating member and the belt from each other; and a detection device for detecting the temperature of the belt. If the detected temperature of the belt reaches a predetermined temperature, an image formation job is interrupted, and the heating member and the belt are separated.
