  A conductive roll to be used as a developing roll, a charging roll, a transfer roll or the like in an electrophotographic apparatus such as a copying machine, a printer or a facsimile, of the present invention comprises a base rubber layer formed on a peripheral surface of a shaft, an intermediate layer formed on a peripheral surface of the base rubber layer, and a surface layer formed on a peripheral surface of the intermediate layer, the surface layer being composed of a resin composition comprising: (A) a silicone-grafted acrylic polymer which comprises repeating units represented by the following general formula (1), wherein an acrylic polymer portion of the silicone-grafted acrylic polymer exclusive of a structural portion derived from a siloxane has a glass-transition temperature of -35 to 30°C:-(Y)k- -(Z)n- (wherein Y is a structural portion derived from an acrylic monomer; Z is a structural portion derived from the acrylic monomer, which has a graft portion derived from a siloxane; k is a positive number of 1 to 3,000; and n is a positive number of 1 to 3,000); and (B) an isocyanate curing agent. According to the present invention, the use of the component (B) enhances the cross-linking of the silicone-component (B) enhances the cross-linking of the silicone-grafted acrylic polymer (A), and thus the surface layer of the conductive roll has an appropriately cross-linked state, so that the conductive roll can be obtained which is superior both in smear resistance and in toner filming resistance.

  A solution (11) containing an organic solvent, a polymer and a plasticizer (TPP, BDP or the like) which is not less than 0.01 wt.% and not more than 50 wt.% of the polymer is cast onto an endless belt (51) to be a casting film (22). Water vapor is condensed from ambient gas on a surface of the casting film (22) passing through a first area (46) to form water drops. The water drops on the casting film (22) passing through a second area (47) are grown and the organic solvent thereof is evaporated. The water drops on the casting film (22) passing through a third area (48) are evaporated. The casting film (22) after passing through the third area (48) is peeled from the endless belt (51) as a flexible porous film (17) by a peel roller (57).

  将含有有机溶剂、聚合物和增塑剂（TPP、BDP 或类似物质）的溶液 (11) 浇注到无缝带 (51) 上，形成浇注膜 (22)，其中聚合物的重量不小于 0.01%，也不大于 50%。水蒸气从通过第一区域 (46) 的浇铸膜 (22) 表面的环境气体中冷凝形成水滴。通过第二区域 (47) 的浇注膜 (22) 上的水滴逐渐增大，其中的有机溶剂被蒸发。通过第三区域 (48) 的浇注膜 (22) 上的水滴被蒸发。通过第三区域 (48) 后的浇铸膜 (22) 由剥离辊 (57) 从无缝带 (51) 上剥离，成为柔性多孔膜 (17)。
