Abstract:
1. An image fixing apparatus which fixes a toner image onto a recording medium, comprising: a pair of rotating members to form a nip-press region through which the recording medium passes; a heater to heat at least one of the pair of rotating members; a temperature sensor to detect a temperature of the at least one of the pair of rotating members; a calculator to calculate a heat value to increase a temperature of the at least one of the pair of rotating members to a target temperature based on a temperature detected by the temperature sensor; a controller to control the heater based on a calculation result of the heat value output by the calculator; a compensator to calculate and generate a delay compensation output by using a delay prediction model according to the calculation result of the calculator; and a selector to select one of a first condition in which the delay compensation output is entered into an input of the calculator and a second condition in which the delay compensation output is not entered into the input of the calculator, wherein the selector selects the first condition when continuously performing an image fixing operation on a plurality of the recording mediums continuously fed.
