摘要： A fixing device includes a fixing rotator, a pressure rotator, a cleaner, a moving assembly, and a temperature detector. The fixing rotator heats and fixes a toner image onto a recording medium. The pressure rotator presses against the fixing rotator. The cleaner contacts and cleans a cleaning target, which includes one of the fixing rotator and the pressure rotator. The moving assembly moves the cleaner between a contact position where the cleaner contacts the cleaning target and a separate position where the cleaner is apart from the cleaning target. The temperature detector detects a temperature of one of the cleaner and the cleaning target. The moving assembly moves the cleaner from the contact position to the separate position or from the separate position to the contact position during rotation of the cleaning target, in a case in which the temperature detected is greater than a given value

摘要： A fixing device includes a first rotator and a second rotator disposed opposite the first rotator. A heater heats one of the first rotator and the second rotator. A cleaner is disposed opposite the second rotator. A temperature detector is disposed opposite the second rotator at an opposed position being within an increased conveyance span where a first sheet is conveyed and being outboard from a decreased conveyance span in an axial direction of the second rotator where a second sheet smaller than the first sheet is conveyed. The temperature detector detects a temperature of the second rotator. A mover moves the cleaner between a contact position where the cleaner contacts the surface of the second rotator and a separation position where the cleaner separates from the surface of the second rotator based on the temperature of the second rotator, that is detected by the temperature detector.

摘要： A fixing device includes a rotatable fuser member a heater, a rotatable pressure member, a thermometer, and a feedback controller. The rotatable fuser member is subjected to heating. The heater heats the fuser member to a heating temperature. The rotatable pressure member is disposed opposite the fuser member. The fuser member and the pressure member are pressed against each other to form a fixing nip therebetween, through which the recording medium is conveyed, so as to fix the toner image in place under heat and pressure. The thermometer is disposed adjacent to the pressure member to detect an operational temperature of the pressure member. The feedback controller is operatively connected with the thermometer to control the heating temperature according to the detected operational temperature, so that the recording medium exhibits a substantially constant post-fixing temperature downstream from the fixing nip regardless of the heat capacity of the recording medium.

摘要： A fixing device includes a fixing rotary body, an opposed member, a heater, and a heating controller. The opposed member opposes the fixing rotary body to form a nipping portion therebetween. The heater includes heat generators arranged in a width direction of a recording medium. When the recording medium fed to the nipping portion has an image area and a non-image area, the heating controller controls the outputs of the heat generators based on image information so that a first heat generator of the heat generators corresponding to the image area is higher in temperature and a second heat generator of the heat generators corresponding to the non-image area is lower in temperature. Based on information other than the image information, the heating controller temporarily shifts an area of the fixing rotary body corresponding to the non-image area to a temperature differing from a normal temperature.
