(Prior Art) Conventionally, a heat roller or press roller used in a heat fixing section of an electronic copying machine or the like has generally been a metal cylinder coated with silicone rubber, fluororubber, or the like. In order to roughly improve the releasability of such rollers from toner, silicone rubber materials are impregnated with silicone oil in advance, and fluorine rubber materials are coated with a fluororesin layer roughly on top of the rubber layer. Processing has been added.

Among these rollers, it is known that a roller having a fluororesin coated on a fluororubber layer has particularly excellent mold release properties. Powder electrostatic coating has conventionally been a common method for coating a fluororesin on a fluororubber layer.

For this reason, the fluororubber was exposed to high temperatures during the firing process, and there was a risk that it would deteriorate. Furthermore, since the fluororubber and fluororesin are only physically attached, they can sometimes peel off during use, which shortens the life of the product.

Another object of the present invention is to provide an excellent heat fixing roller.

[Structure of the Invention] (Means for Solving the Problems) The heat fixing roller of the present invention coats and cures a rubbery composition on the roll core shaft to form a rubber layer, and a rubbery composition is coated on the surface of the rubber layer. It is constructed by forming a synthetic resin coating by plasma polymerizing a crosslinkable polymerizable monomer that can be copolymerized with the composition. Plasma polymerization has a more complex reaction mechanism than general polymerization reactions, and involves a large number of reactions, and the entire mechanism has not yet been clarified at present.

In the reaction under discharge, electrons mainly have a resistance of 1Ω, and these electrons collide with molecules in the gas phase or attached to the solid surface, producing so-called active species such as radicals, ions, atoms in active states, and molecules. These active species, electrons, and particles are mixed with ordinary molecules, and many more reactions occur. Furthermore, these reactions do not simply occur in the gas phase, but also reactions between the gas phase and the same phase, surface reactions on solid surfaces, adsorption,
The polymerization mechanism has become even more complex due to the involvement of physical phenomena such as desorption. Polymers produced by plasma polymerization have features such as having a sophisticated network structure, excellent chemical resistance and heat resistance, and almost no pinholes. During the polymerization process, the crosslinkable monomer forms a network structure while crosslinking with the rubber layer, which becomes a gas phase, to form a synthetic resin coating, so the rubber layer and synthetic resin coating form a strong chemical bond. .

Furthermore, unlike the conventional method of applying a fluororesin coating or a silicone resin coating using powder electrostatic coating, there is no need for a baking process at high temperatures. Therefore, there is no fear of deteriorating the rubber layer, the manufacturing process can be shortened, and the cost can be reduced. Since the synthetic resin layer formed by plasma polymerization has excellent heat resistance, it is possible to raise the fixing temperature in the heat-fixing section, and it is necessary to be able to cope with high-speed copying machines. In addition, the coating is less prone to pinholes, so
The releasability from the toner can be further improved compared to conventional rollers that have a synthetic resin layer formed by an electrostatic powder coating layer.
