ELECTROPHOTOGRAPHIC MEMBER, IMAGE HEATING DEVICE, IMAGE FORMING APPARATUS AND MANUFACTURING METHOD OF ELECTROPHOTOGRAPHIC MEMBER

PROBLEM TO BE SOLVED: To provide an electrophotographic member having an elastic layer including silicone rubber and a mold release layer including a fluorine resin sufficiently adhered to each other without requiring an adhesion layer therebetween.SOLUTION: There is provided an electrophotographic member includes a base material, an elastic layer including silicone rubber on the base material, and a mold release layer provided directly on the surface of the elastic layer, where the mold release agent includes a fluorine resin selected from the group consisting of PFA, FEP, PTFE, ETFE, PCTFE, ECTFE, and PVDF, and the elastic layer causes cohesive failure in 90° peel strength test based on Japan Industrial Standard (JIS)K6854-1:1999.SELECTED DRAWING: Figure 1 【課題】 接着層を介さずに、シリコーンゴムを含む弾性層とフッ素樹脂を含む離型層とが十分に接着された電子写真用部材を提供する。【解決手段】 電子写真用部材は、基材、該基材上のシリコーンゴムを含む弾性層、該弾性層の表面上に直接接して設けられた離型層を有し、該離型層が、ＰＦＡ、ＦＥＰ、ＰＴＦＥ、ＥＴＦＥ、ＰＣＴＦＥ、ＥＣＴＦＥ及びＰＶＤＦからなる群より選ばれるフッ素樹脂を含み、日本工業規格（ＪＩＳ） Ｋ ６８５４−１：１９９９で規定される９０°はく離接着強さ試験において、該弾性層が凝集破壊を起こす。【選択図】 図１
