摘要： In a fixing device, a second rotary member disposed opposite a first rotary member forms a nip between the first rotary member and the second rotary member through which a recording medium bearing a toner image passes. A first separation member rotatively provided on a rotary shaft of the first rotary member separates the recording medium passing through the nip from the first rotary member. A rotation angle adjuster connected to the first separation member changes a rotation angle position of the first separation member.

The flexible endless belt is disposed on an outer circumferential surface of the fixing member. The rotary pressure member is disposed parallel to and pressing against the fixing member via the endless belt. The heating unit heats the endless belt. The rotation detector detects a rotation speed of the endless belt. The heating unit is powered off when the rotation speed of the endless belt detected by the rotation detector is at or below a predetermined threshold value.
