摘要： This invention provides a process for producing a conductive rubber roller having small aspect ratios of inner and outer diameters, having a stable measure of its inner diameter, having uniform cell distribution and being free from non-uniformity of hardness and electrical resistance in the peripheral direction. The process has a step of continuously extruding a tube composed of a specific unvulcanized rubber composition from a rubber extruder in a microwave vulcanizing unit, and a step of foaming and vulcanizing the tube by using a microwave irradiator having a microwave irradiation zone 4 m or less in length while being transported at given speed. The foamed rubber tube has an inner diameter 20 to 35% smaller than the outer diameter of the conductive core material over the whole region in the lengthwise direction, and the conductive core material is press-fitted into the foamed rubber tube without using any adhesive.

摘要： A process for producing a conductive rubber roller having a conductive core material and a rubber layer provided thereon. The rubber layer contains at least acrylonitrile rubber, epichlorohydrin rubber and a blowing agent, and has a gas generation rate of from 2 ml/g·min to 4 ml/g·min at 170° C. to 230° C. The process has a vulcanizing and foaming step of vulcanizing and foaming the rubber layer by using a microwave vulcanizing furnace which provides hot air and irradiation with microwaves. A temperature of a heating atmosphere in the microwave vulcanizing furnace in the vulcanizing and foaming step is so controlled that a ratio of initial vulcanizing time T10 to initial foaming time Tp10, T10/Tp10, of the rubber layer is from 1 or more to less than 3 and the T10 is within 90 seconds.
