| 发明名称 | Member for electrophotography, fixing device, and electrophotographic image forming apparatus | ||
| 摘要 | Provided is a member for electrophotography including a fluorine resin surface layer formed by melting fluorine resin powder, the member being capable of stably maintaining rubber elasticity over a long time period. Further, provided are a fixing member, a fixing device, and an electrophotographic image forming apparatus each capable of stably providing the image quality of an electrophotographic image. The member for electrophotography is a member for electrophotography, comprising: a substrate; a cured silicone rubber elastic layer; and a fluorine resin surface layer obtained by melting a fluorine resin powder, wherein: when a microhardness of a cured rubber forming the cured silicone rubber elastic layer is defined as Hμ0, and a microhardness of a rubber obtained by soaking the cured rubber in a methyl hydrogen silicone oil for 24 hours, and then further curing the cured rubber is defined as Hμ1, Hμ1/Hμ0 is 2.5 or more and 5.0 or less. | ||

| 主权项 | 1. A member for electrophotography, comprising: a substrate; a cured silicone rubber elastic layer comprising an unsaturated aliphatic group; and a fluorine resin surface layer obtained by melting a fluorine resin powder on the cured silicone rubber elastic layer, wherein: when a microhardness of a cured rubber forming the cured silicone rubber elastic layer is defined as Hμ0, and when a microhardness of a rubber obtained by soaking the cured rubber in a methyl hydrogen silicone oil for 24 hours, and then further curing the cured rubber is defined as Hμ1, Hμ1/Hμ0 is from 2.5 to 5.0. | ||
