ABSTRACT:
Because the present invention produces a toner-fixing roll by forming, directly or indirectly, a layer of thermal stabilizer-containing cured silicone rubber on the circumferential surface of a core and by then heating the cured silicone rubber layer at 270.degree. C. to 400.degree. C. for 15 minutes to 24 hours, said toner-fixing roll has excellent releasability with regard to fused toner without the use of silicone oil. Due to this, the silicone rubber-coated roll produced by the method of the present invention is appropriately employed as a toner-fixing roll in dry electrophotographic devices, that is, it is suitable for the heat-fixing roll or pressure roll and particularly for the heat-fixing roll.
