Fixing device and image forming apparatus having temperature detector

A fixing device comprising:

• a fixing rotator formed into a loop and rotatable in a predetermined direction of rotation;
• a pressure rotator disposed outside the loop formed by the fixing rotator and pressed against the fixing rotator to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed;
• a stay disposed opposite the pressure rotator via the fixing rotator;
• a heater disposed opposite an inner circumferential surface of the fixing rotator to heat the fixing rotator;
• a pressurization member pressed against the heater via the fixing rotator;
• a housing interposed between the stay and the heater;
• a temperature detector mounted on the housing to detect a temperature of the heater;
• and
• a heater holder holding the heater and attached with the housing,
• wherein the housing includes a plurality of housing positioners aligned in a longitudinal direction of the housing, and
• wherein the housing further includes a temperature detector holder, interposed between adjacent housing positioners of the plurality of housing positioners in the longitudinal direction of the housing, to engage the temperature detector.
