Abstract

PROBLEM TO BE SOLVED: To provide a plate heater in which temperature rising property can be improved by reducing heat capacity of a substrate to the resistance heating element by regulating the width of the long substrate and the forming width of the resistance heating element formed on this substrate, and in which occurrence of crack of the substrate can be suppressed, and to provide a fixing device using this plate heater, and an image forming apparatus installed with this fixing device. SOLUTION: The plate heater H1 which comprises a long substrate 1 made of a material having thermal resistance and electric insulation, a resistance heating element 2 which is formed in belt shape with a width 70% or more of the width of the substrate along the longitudinal direction on the surface of the substrate 1 and contains glass, inorganic oxide and / or inorganic nitride in Ag-Pd alloy, and power supply terminal parts 3, 3 formed connected to this resistance heating element 2, and the fixing device 7 using the plate heater H1 and the image forming apparatus 9 installed with the fixing device 7 are provided.

Description

technical field

[0001] The present invention relates to a plate-shaped heater used as a heating source in OA equipment, household appliances, precision manufacturing equipment, and experimental research equipment, etc., and a toner fixing device for OA equipment such as copiers and facsimile machines equipped with the plate-shaped heater. And an image forming apparatus equipped with the fixing device. Background technique

[0002] For example, in an electronic copier, the toner image formed on the surface of the photosensitive drum is transferred to a copy paper and a copy film as a heated body, and then the copy paper is pressed between a plate heater and a pressure roller. , while passing the copy paper therebetween, the copy paper is heated by the heat of the plate heater to fuse the toner and fix it.

[0003] In this conventional plate heater, the Al 2 o 3 (Aluminum Oxide), AlN (Aluminum Nitride) or SiC (Silicon Carbide) and other heat-resistant and electrically insul...
