摘要： An image forming apparatus includes an image forming device that forms a toner image on a recording medium, a first rotator, and a second rotator that presses against the first rotator to form a nip therebetween. The first rotator conveys the recording medium bearing the toner image through the nip with a first orientation of the recording medium to fix the toner image on the recording medium to create a cleaning sheet bearing a cleaning image in a cleaning sheet creation mode. The first rotator conveys the cleaning sheet bearing the cleaning image through the nip with a second orientation of the cleaning sheet, that is different from the first orientation of the recording medium, such that the cleaning image is disposed opposite the first rotator to cause the cleaning image to remove a foreign substance from a surface of the first rotator in a cleaning mode.

摘要： A fixing device includes a fixing rotator, a pressure rotator, a cleaner, and a moving assembly. 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 at which the cleaner contacts the cleaning target and a separate position at which the cleaner is apart from the cleaning target. The moving assembly includes a biasing member that presses the cleaner to move to the contact position. The moving assembly moves the cleaner from the contact position to the separate position against a biasing force of the biasing member. The moving assembly moves the cleaner from the separate position to the contact position while increasing and then decreasing the biasing force of the biasing member greater than the biasing force applied when the cleaner is located at the contact position.

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 opposing the fixing rotary body to form a nipping portion, and a heater to heat the fixing rotary body. The heater includes heat generators arranged in a width direction of a recording medium and separately supplied with power. When an unfixed image on the medium has an image area and a non-image area, power supplied to each of the heat generators is controlled so that, of the heat generators, a first heat generator corresponding to the image area becomes a higher temperature and second heat generators corresponding to the non-image area becomes a lower temperature. When the second heat generators are adjacent to each other, power supplied to one of the second heat generators closer to the image area is set to be greater than power supplied to another of the second heat generators farther from the image area.

摘要： A temperature control method of calculating a temperature of a recording medium after fixing and used in a thermal fixing device includes separating calculations of calculating the temperature of the recording medium after fixing into first-stage calculations to be performed before start of printing and second-stage calculations to be performed in real time during the printing, performing the first-stage calculations, and performing the second-stage calculations to calculate a result of the temperature of the recording medium after fixing. Further, the result of the temperature of the recording medium after fixing is used to control obtaining a desired temperature of the recording medium after fixing, and the temperature of the recording medium after fixing is calculated without directly measuring the temperature of the recording medium after fixing.

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.
