    • 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.
    • 因为本发明通过直接或间接地在芯的圆周表面上形成一层含热稳定剂的固化的硅橡胶,然后在270℃加热固化的硅橡胶层至400℃来生产调色剂定影辊 在15分钟至24小时内,所述调色剂定影辊在不使用硅油的情况下对熔融调色剂具有优异的脱模性。 因此,通过本发明的方法制造的硅橡胶涂布辊适用于干电子照相装置中的调色剂定影辊,即适用于热定影辊或压辊,特别适用于 热定影辊。
