PRODUCTION OF MULTILAYERED ROLLER

摘要

PURPOSE:To produce a multilayered roller excellent in durability and thermal responsiveness and adaptable to a high speed copier. CONSTITUTION:A coating soln. prepared by adding an equal amt. mixture of a carbon type surfactant and a fluorine type surfactant to a fluoroplastic dispersion is applied to the elastomer layer 3 formed on a core metal 2. This coating soln. is enhanced in film forming properties and can be thinly applied and the mechanical strength of the formed fluoroplastic layer 4 is markedly enhanced in mechanical strength. By this constitution, the fluoroplastic layer 4 is thin and the obtained multilayered roller is enhanced in thermal responsiveness and can be adapted to a high speed copier.
