摘要：
A heat plate for fixation includes: a metallic base plate; and a heating resistor arranged on a reverse face of the metallic base plate, the heating resistor being formed by laminating, at least, an electric insulating layer and heating resistor layer in this order on the metallic base plate, wherein the heat plate is capable of raising the temperature of the metallic base plate to a fixing temperature when the heating resistor layer is energized and heated. A semicircular heating member for fixation includes the heat plate which is curved so that the metallic base plate has a convex surface, a belt type fixing device is provided with the semicircular heating member, and an electrophotographic image forming apparatus is provided with the belt type fixing device having the semicircular heating member.
