Latest Patents

One of Namiki's latest patents is an image fixing device designed for electrophotographic copying apparatuses. This device includes a fixing roller and a pressing roller that are in pressing contact with each other. The fixing roller is composed of a metallic core, a resilient material layer, and an offset preventing layer, all arranged in a specific order. The heating member within the fixing roller heats the metallic core, allowing a copy sheet with a toner image to pass between the two rolls. This process ensures that the toner image is fixed to the copy sheet through melt adhesion while being heated. The offset preventing layer is engineered to have a higher heat intake than the toner image, ensuring a responsive heat application. It is made from a synthetic resinous material, such as silicone rubber, which is highly resistant to heat and has excellent parting properties, enhanced with metal powder for improved thermal conductivity.

Another notable patent involves a method for forming a protective layer on a rubber roller that is supplied with oil during use. This method includes beveling the end faces of the roller to create a protective layer that prevents oil penetration, which can degrade the rubber roller over time.
