    摘要： An image heating apparatus that enables a temperature of an image heating element to be stably maintained at a target temperature as a fixing speed varies. A Proportional-Integral-Derivative (PID) controller determines whether a temperature control computation results in a range that allows temperature control with one IGBT, and a linear control is performed if the result is at least equal to a minimum power obtained as IH output. PWM control is performed at minimum power if the power is less than a required minimum power. Thus, a computation method of a supply power computator need not be switched according to the fixing speed, and a calorific value of a fixing belt can be controlled using one computation method.

    摘要： An image heating apparatus is provided that enables the temperature of an image heating element to be maintained stably at a target temperature even when the fixing speed varies, and that enables lower cost and higher efficiency to be achieved. In this apparatus, with a calorific value control section 300 of a fixing apparatus 200, temperature control computation is not varied according to the rotational speed of a fixing belt 230, but it is determined whether a PID control computation result is in a range that allows temperature control with one IGBT, linear control is performed if the result is greater than or equal to the minimum power obtained as IH output, and PWM control is performed at minimum power if power less than or equal to the minimum power is required. It is thus not necessary for the computation method of a supply power computation section 301 to be switched according to the fixing speed, and the calorific value of fixing belt 230 can be controlled with one computation method. Therefore, the supply power to the heat source of fixing belt 230 can be PID-controlled by only one switching element (IGBT), lower cost and higher efficiency can be achieved, and the temperature of fixing belt 230 can be maintained stably at the target temperature.

    摘要： An image fixing device that is controllable with a high degree of reliability. The image fixing device is configured with a heat generator for fixing a toner image onto a recording medium that is opposed to an induction heater. Heat is generated in the heat generator through electromagnetic induction. An inverter circuit drives the induction heater. A power controller controls a power value that is output from the inverter circuit, whose power value is calculated by a power-value calculator. A power-value sensor acquires the power value output from the power controller, and a temperature sensor senses a temperature at least at one point of the heat generator. Thus, either the power value sensed by the power-value sensor or a temperature value sensed by the temperature sensor may be used as a reference value to calculate the power value in the power-value calculator.
