Patent ID: 7039335

Claim:
A heat fixing device for fixing a medium to another medium, the heat fixing device comprising: an attachment member; a thermal fixing member that generates heat for thermally fixing the medium to the other medium; and a temperature sensor including: a substantially rigid support member having an attachment section, a contact section, and a bend, the attachment section and the bend being on opposite ends of the contact section, the contact section having an upper surface and a lower surface that are opposite surfaces of the contact section and that are separated from each other in a direction from the lower surface to the upper surface of the contact section, the attachment section being attached to the attachment member with the lower surface of the contact section in contact with the thermal fixing member, the bend having a lower surface that slants away from the lower surface of the contact section in the direction from the lower surface to the upper surface of the contact section, the lower surface of the bend and the lower surface of the contact section forming a rounded corner portion; and a temperature detecting element for detecting the temperature of the thermal fixing member, the temperature detecting element being fixed on the support member.
