摘要： An image forming apparatus includes a first heater disposed opposite and heating at least a center of a fixing belt in an axial direction thereof and a second heater disposed opposite and heating at least a lateral end of the fixing belt in the axial direction thereof. A power supply supplies power to the first heater and the second heater. A controller that controls the power supply includes a calculator to calculate an elapsed time elapsed after at least one of the first heater and the second heater starts heating the fixing belt. The controller controls the power supply to supply power to the first heater and the second heater such that a power density of the second heater is greater than a power density of the first heater when the elapsed time calculated by the calculator is smaller than a predetermined time.

摘要： An image forming apparatus includes an image forming part, a fixer including a heating member and a pressure member, a reverse transport part to forward a recording medium transported from the fixer to the image forming part, a toner image sensor to detect presence of a toner image on the recording medium, and a controller. When a glossy image formation mode is selected and no toner image is detected on the recording medium, the image forming part does not form a toner image on the recording medium, the fixer performs a first heating and pressing process and transports the recording medium to the reverse transport part, the reverse transport part transports the recording medium to the image forming part, the image forming part forms a toner image on the recording medium transported from the reverse transport part, and the fixer performs a second heating and pressing process and fixes the toner image thereon.

摘要： A fixing device includes a heating member that heats an unfixed toner image on a printing medium, a conveyance device that conveys the printing medium launched from the heating member after the heating member heats the unfixed toner image, and a heat temperature detection device that detects heat temperature of the heating member. An excessive temperature rise prevention device is provided to forcibly cut off power distribution to the heating member when the heat temperature reaches an abnormal level. A cooling device is provided to cool the excessive temperature rise prevention device. Further provided is a cooling device use control device that controls the cooling device to cool the excessive temperature rise prevention device when the conveyance device stops a conveyance operation.
