Latest Patents
One of Hiroshi Imasaka's latest patents is a process for producing a conductive rubber roller and a roller for electrophotographic apparatus. This invention provides a method for creating a conductive rubber roller with small aspect ratios of inner and outer diameters. It ensures a stable measurement of the inner diameter, uniform cell distribution, and eliminates non-uniformity of hardness and electrical resistance in the peripheral direction. The process involves continuously extruding a tube made from a specific unvulcanized rubber composition in a microwave vulcanizing unit. It also includes foaming and vulcanizing the tube using a microwave irradiator while being transported at a specified speed. The resulting foamed rubber tube has an inner diameter that is 20 to 35% smaller than the outer diameter of the conductive core material, allowing for a press-fit without the use of adhesives.
