Publication number: 20240103414Abstract: A fixing unit or device that can be used in an image forming apparatus includes a first heater element that is formed of a material that increases in electrical resistance with increases in temperature. A controller of the fixing unit is configured to vary a duty ratio of electric power applied to the first heater element during a start-up operation in which the temperature of the first heater element is raised to a target operating temperature. By varying the duty ratio during the start-up operation, changes in the resistance of the first heater element with the heating can be compensated. For example, the duty ratio can be increased during the course of the start-up to achieve the target operating temperature faster.Type: ApplicationFiled: December 1, 2023Publication date: March 28, 2024Inventors: Kiyotaka MURAKAMI, Kazuhiko KIKUCHI, Sasuke ENDO, Masaya TANAKA, Ryota SAEKI, Kousei MIYASHITA, Ryosuke KOJIMA, Yohei DOI, Yuki KAWASHIMA, Eiji SHINOHARA
