Components in which the materials from which they are made must be functional are called functional components. These include components used in Canon copying machines and laser beam printers such as highimage- quality fixing materials, electrostatic transfer and intermediate transfer belts, electric separation transfer and electrical charging rollers, and low friction blades. Canon carries out detailed analyses of the physical phenomena that take place during each process of a product's operation. After thoroughly assessing the necessary properties, the company proceeds to develop materials capable of delivering the required functions in a well-balanced manner.
