Abstract
An image recording apparatus comprising a heat roll for fusing an toner image transferred onto a sheet by heating; a switching device for starting conduction of a heater installed within the heat roll; a temperature control device for controlling the surface temperature of the heat roll in a first predetermined temperature by controlling conduction of the heater when the switching device has been turned on and for controlling the surface temperature of the heat roll by increasing the surface temperature from a first temperature to a second predetermined temperature being different from the first temperature in response to a control signal; and a control device for applying the control signal to the temperature control device to approximately maintain the surface temperature of the heat roll in at least one of the first temperature and the second temperature.
