摘要： Energy saving in a fixing unit having a low heat capacity is achieved by reducing a loss of heat transferring from a temperature sensing element to temperature sensing unit and by improving response of the safety device. A heat-insulating member is formed to cover a temperature fuse being a temperature sensing element and a heat-conductive filler or heat-conductive elastic member is formed between the temperature fuse and a sliding sheet. A temperature sensing means having the temperature sensing element abuts on a fixing roller through a sliding sheet interposed therebetween. A contacting portion of the temperature sensing means with the heat-insulating member and the filler or elastic member has a curved contacting surface fitting a cylindrical surface of the fixing roller. The heat-insulating member has a groove or a slit for engaging with a protrusion of the temperature sensing element to be secured to the heat-insulating member.
