Abstract
An endless belt for heating an image on a sheet includes a resistance layer for generating heat by the supply of electric power; a first ring member provided in a widthwise end side of the endless belt so as to be electrically connected with the resistance layer; a second ring member, one of the first and second ring members being fitted around the other with the resistance layer sandwiched therebetween; and a fixing member configured to fix the first and second ring members to each other so that the first and second ring members are rotated integrally with the resistance layer.
