Publication number: 20220317607Abstract: A temperature detection section is disposed opposite to a heater so as to be out of contact with the heater, and detects a temperature of the heating element. A spacer is disposed so that the heater and the temperature detection section are out of contact with each other. The spacer includes a separator that separates the temperature detection section from the heater and that has a gap through which the heat is transferred from the heater to the temperature detection section and that melts upon the temperature of the heating element increasing to a specific temperature or higher. The separator after melting fills the gap.Type: ApplicationFiled: March 25, 2022Publication date: October 6, 2022Applicant: KYOCERA Document Solutions Inc.Inventors: Tomohiro WATATANI, Yuhiro SAKAI, Takashi EIKI, Ryohei TOKUNAGA, Akihiro KONDO, Yuta KITABAYASHI, Rina KIKUGAWA, Hiroki KAWASAKI, Shunsaku FUJII, Tei TO
