QUICK HEAT ROLLER

摘要

A quick heat roller used for fixing in an electrophotographic device, capable of a long service life and a high-speed heating and kept at a constant temperature, the roller comprising: a heating resistor sheet (8) formed by forming on the surface of an insulating layer (20) of a polyimide resin sheet a heating resistor layer (22) by silk screen printing, bonding a polyimide resin sheet as an insulating layer (24) and bonding on the surface thereof a heat reflection layer (26) of an aluminum foil; and a cylindrical body (6) which is formed by providing on the outer peripheral surface of an aluminum tube a releasing layer (4) for preventing the deposition of a developing toner and which has its inner peripheral surface pasted with the above heating resistor sheet (8).
