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： A fixing unit includes a fixing member, a pressing member, a heating device, a sheet width detector, and a heating area adjustor. The pressing member faces the fixing member to form a fixing nip between the fixing member. An un-fixed toner image is fixed on a recording medium when the recording medium passes through the fixing nip. The heating device heats the fixing member while maintaining a non-contact condition with the fixing member. The sheet width detector detects sheet width of the recording medium. The heating area adjustor changes a heating area of the fixing member, heatable by the heating device, based on the sheet width detected by the sheet width detector. The heating area adjustor is moveable in a space between the fixing member and the heating device along a sheet width direction to change a size of the heating area.
