Abstract

PURPOSE: To obtain the images of good resolution by providing a glassy layer on the surface of a heat roll, building a heat source for heating in said roll and providing a silicone rubber layer on the surface of a backup roll.
CONSTITUTION: The recording member 1 formed with powder toner images 2 passes between a heat roll 3 and backup roll 9 and is thereby fixed. The roll 3, provided with a glassy layer 5 on its metal substrate 4, is made through porcelain enamel finish comprising firing plaze at 600W1000°C. A coil heater 7 is disposed in a glass rod 8 in the core shaft 6 of the heat roll 3. The backup roll 9 is provided with a heat-resistant silicone rubber layer 11 of 2mm or over in thickness and 30W60 in rubber hardness on its core material 10 of copper, alumina, etc. The glass layer on the surface of the heat roll 3 is high in hardness, long in service life and permits heating up to 300°C and higher, and therefore even if the heat roll is a rigid body, the images of good resolution may be obtained.
