<p>PURPOSE:To provide a heater that can provide a predetermined resistance value at accuracy, a method of manufacture of the heater, and a fixing device that uses the heater. CONSTITUTION:A heater H comprising a resistance heating element 2 having a band heating portion in at least one part thereof and printed on an insulated substrate 1, the edge of the resistance heating element 2 being longitudinally trimmed 6(5) on a straight line 3b with no corners and on a curved continuous line 3a, a method of manufacture of the heater, and a fixing device having the heater H are disclosed. The heater causing no damage to the trimmed (cut) part of the resistance heating element 2 and having a high-accuracy resistance value range (+ or -3%) can readily be obtained, and no bubble remains in a glass coating layer on the surface of the heater and so the coating layer is not damaged, and when the heater H is assembled into the fixing device, image contrast failure and fixing unevenness, etc., can be prevented.</p> |
