  • Fixing For Electrophotography (AREA)

Abstract

PURPOSE: To prevent the occurrence of offset to rolls in powder toner fixing of an electrophotographic process by forming the heat fixing roll with the silicone rubber containing fine powder silica adsorbed with silicone oil.
CONSTITUTION: An oil compound is formed by adding about 10 to 20 wt.% of fine powder silica (preferably about several tens nm in particle size) to a silicone oil of superior high temperature stability such as dimethyl silicone oil or methyl phenyl silicone oil. This is then incorporated at about 10 to 15 wt.% into silicone rubber (preferably room temperature curing type) and the compound is molded and crosslinked to form the heat fixing roll. It is desirable that the abovementioned oil compound exist more in the portions closer to the central part of the roll and it is recommended to laminated and form the oil compound rich rubber layer and the coil compound poor rubber layer in this order on the roll base.
