Abstract:
An image forming apparatus, comprising:a fixing mechanism, comprising a heater, configured to fix a toner image on a recording sheet at a fixing position; a power source configured to drive the heater; a sheet transfer mechanism configured to transfer said recording sheet from a sheet cassette to an eject tray via said fixing position; and a controller to change a sheet transfer speed upon varying an image resolution, to instruct said power source to drive said heater to increase a temperature of said heater up to a goal temperature, to set said goal temperature to a predetermined value when said sheet transfer speed is greater than a predetermined speed, to control said temperature of said heater via said power source by varying said goal temperature in accordance with values of said sheet transfer speed when said sheet transfer speed is smaller than said predetermined speed and to start a sheet transfer operation at a time before said heater reaches said goal temperature so that a recording sheet arrives at said fixing position when a temperature of said heater reaches said goal temperature.
