Claim Text:
1. A fixing apparatus comprising: a heating unit configured to heat a heated object which is either a roller or an endless belt stretched around a plurality of rollers; an another roller pressed into contact with the heated object in order to form a nip portion between the another roller and the heated object; and a control unit configured to control the temperature of the heated object by controlling the heating unit, the fixing apparatus being configured to fix an unfixed toner image formed on a continuous paper to the continuous paper by heat from the heated object under a nipping pressure applied at the nip portion, wherein the control unit controls the temperature of the heated object to be a stand-by temperature lower than such a first temperature, which is set up in advance, that paper trouble might occur if the continuous paper is continuously heated at a temperature not lower than the first temperature in a stand-by state in which fixing is not performed; wherein, when a job execution command is issued to perform image formation in the stand-by state, the control unit controls the heating unit to elevate the temperature of the heated object so that the temperature of the heated object rises from the stand-by temperature to a target temperature higher than the first temperature, and to lower the temperature of the heated object in advance of completing the job so that the temperature of the heated object has reached the stand-by temperature lower than the first temperature at the time when the job is completed.
