Application: Image forming apparatus and heating method (Patent ID: US20240103414A1)
The patent filed by Toshiba Corp. describes a fixing unit for an image forming apparatus that includes a first heater element with increasing electrical resistance as temperature rises. The controller of the fixing unit adjusts the duty ratio of electric power applied to the first heater element during start-up to reach the target operating temperature efficiently. By varying the duty ratio, changes in resistance with heating can be compensated, allowing for faster achievement of the target temperature.
The fixing unit also includes a second heater element and a controller that varies the duty ratio of electric power applied to both heater elements based on specific conditions being satisfied. These conditions include start-up from an idle or unheated state, with the controller increasing the duty ratio of electric power applied to the first heater element at fixed time intervals. Additionally, sensors for heater temperature, film temperature, and ambient temperature are used to determine whether the conditions for adjusting the duty ratio are met. Overall, the patent focuses on optimizing the heating process of the fixing unit in an image forming apparatus to improve efficiency and performance.
