Abstract
The fixing device includes: a fixing member including a conductive layer capable of self-heating by electromagnetic induction; a drive unit rotationally driving the fixing member; a magnetic field generating member generating an alternate-current magnetic field intersecting with the conductive layer; a fixation pressing member movable so as to come into pressure contact with an outer circumferential surface of the fixing member and to separate from the outer circumferential surface; and a temperature measurement unit that includes a temperature detector and a support portion, that measures temperature of the fixing member with the temperature detector which is pressed by the support portion to be brought into contact with an inner circumferential surface of the fixing member, and that holds a contact state between the temperature detector and the inner circumferential surface in every state where the fixing member is displaced in accordance with movement of the fixation pressing member.
