摘要： A fixing device includes: a fixing member; an opposing member that provides a fixing nip with the fixing member; a heating unit that heats the fixing member; a heating area changing member that moves to change a heating area of the fixing member heated by the heating unit; and a position detection sensor that detects a position of the heating area changing member. The fixing device controls a stop position of the heating area changing member based on detection by the position detection sensor. The single position detection sensor detects the position of the heating area changing member both when the heating area changing member is moving from a preset reference position to an arbitrary position and when the heating area changing member is moving back from an arbitrary position to the reference position.

摘要： A fixing device includes a thermal conductor disposed inside a flexible endless fixing belt formed into a loop and configured to conduct heat from a heater to the fixing belt. The thermal conductor includes a center heating portion heated by the heater and disposed at a center of the thermal conductor in a longitudinal direction thereof orthogonal to a conveyance direction of a recording medium conveyed to the fixing belt and lateral end non-heating portions disposed at lateral ends of the thermal conductor in the longitudinal direction thereof and contiguous to the center heating portion. The center heating portion having a first diameter conducts heat from the heater to the fixing belt. The lateral end non-heating portions having a second diameter smaller than the first diameter of the center heating portion minimize conduction of heat from the heater to the fixing belt.
