Abstract: A image forming apparatus includes: a fixing member; a blowing section that generates airflow toward the fixing nip, the airflow being used for separating a sheet from the fixing member; and a hardware processor that performs a control of causing airflow amounts of the blowing section to be different in an axial direction of the fixing member so that part of the airflow flowing from the blowing section toward a non-sheet-passing region of the fixing nip is directed toward the fixing member.

Abstract: A fixing device includes: a fixer that includes a heater controlled and lighted on the basis of a detection result of a temperature sensor, and melts and fixes an unfixed toner on a recording medium, using heat of when the heater is lighted; a lighting rate acquirer that acquires a first lighting rate of the heater after jam recovery and a second lighting rate of the heater before jam occurrence in a case where a jam of the recording medium occurs at a fixing nip position of the fixer; and a determiner that compares the first lighting rate with the second lighting rate, and determines whether the recording medium remains between the temperature sensor and the heater according to a result of the comparison.
