ABSTRACT:
A fixing roller for a fixing unit for a copying machine has a heater disposed within an aluminum cylinder. A pair of stainless steel, U-shaped plates, which have holes cut in their bottoms, are fitted into opposite end portions of the cylinder to hold the heater and to utilize the heat generated thereby. A pair of bearings, which have outer races made of heat-resistant resin, are fitted into the opposite end portions of the cylinder under pressure to support the cylinder so that the outer races and the cylinder turn as one unit.
