摘要： An image forming apparatus includes a heating device including a heat generator and a resistance value identifier, a body, a resistance value acquisition unit, a detector to detect detachment and attachment of the heating device from and to the body, and an electric power controller. The resistance value identifier corresponds to a resistance value of the heat generator. The resistance value acquisition unit acquires the resistance value from the resistance value identifier. The electric power controller causes the resistance value acquisition unit to acquire the resistance value when the detector detects detachment and attachment of the heating device. The electric power controller changes a lighting duty of the heat generator when the acquired resistance value of the heat generator is different from the resistance value before the detector detects detachment and attachment of the heating device.

摘要： A heating device includes a belt that rotates in a rotation direction and has a temperature decrease span in an axial direction of the belt, where the belt is susceptible to temperature decrease. A resistive heat generator is disposed opposite the belt. The resistive heat generator heats the belt and extends in the axial direction of the belt. The resistive heat generator includes a primary heat generating portion that generates heat in a first heat generation amount and a secondary heat generating portion that is disposed outside the primary heat generating portion and disposed opposite the temperature decrease span of the belt. The secondary heat generating portion generates heat in a second heat generation amount that is greater than the first heat generation amount of the primary heat generating portion.

摘要： An image forming apparatus includes a power controller that starts an examination mode by an external operation. The examination mode detects a temperature-resistance property of a resistive heat generator. The power controller supplies power at a predetermined power duty cycle to the resistive heat generator. The power controller obtains the power supplied to the resistive heat generator and a change in a temperature of the resistive heat generator, that is detected by a temperature detector, while the power controller supplies the power at the predetermined power duty cycle to the resistive heat generator. The power controller calculates the temperature-resistance property of the resistive heat generator based on the power and the change in the temperature that are obtained. The power controller adjusts a power duty cycle at which the power is supplied to the resistive heat generator based on the temperature-resistance property.

摘要： Disclosed is a fixing device including a liquid supply unit that supplies a liquid fixer containing a softening agent that dissolves or swells at least part of resin to soften the resin; an air supply unit that supplies air for foaming the liquid fixer; and a foam generation unit that mixes the liquid fixer from the liquid supply unit with the air from the air supply unit to generate foams. The foam generation unit has an air channel where the air from the air supply unit flows, a liquid-fixer channel provided such that the liquid fixer from the liquid supply unit flows from a direction opposite to a flowing direction of the air channel, and an air-and-liquid mixing part that mixes the air from the air channel with the liquid fixer from the liquid fixer channel so as to be opposite to each other, thereby generating a foam-like fixer.

摘要： A fixing device including a fixing belt, a drive roller and a press roller. The drive roller is configured to drive the fixing belt, and press roller is arranged so as to face the drive roller across the fixing belt, and exert pressure toward the fixing belt. The drive roller and the press roller are able to rotate so that the peripheral velocity of the drive roller is greater than the peripheral velocity of the press roller. According to the fixing device image defects, including image difference, are less likely to occur when fixing an image on a recording sheet.
