Abstract
(EN)
A developing roller 1 is provided with: an elastic layer 3 formed on the outer circumferential surface of a shaft body 2; and a coat layer 4 formed on the outer circumferential surface of the elastic layer 3, wherein the coat layer 4 is formed by thermally curing a resin composition for the coat layer which contains a polyol (a), an isocyanate (b), a surface roughness material (c), and a conductive material (d) and the polyol (a) contains a polyol (a1) having an unreactive silicone group in a side chain and/or a monoterminal diol-type silicone oil (a2).
(FR)
La présente invention concerne un rouleau de développement 1 qui est pourvu : d'une couche élastique 3 formée sur la surface circonférentielle externe d'un corps d'arbre 2 ; et d'une couche de revêtement 4 formée sur la surface circonférentielle externe de la couche élastique 3, la couche de revêtement 4 étant formée par le durcissement thermique d'une composition de résine qui est destinée à être utilisée avec la couche de revêtement et qui contient un polyol (a), un isocyanate (b), un matériau de rugosité de surface (c) et un matériau conducteur (d), et le polyol (a) contient un polyol (a1) ayant un groupe silicone non réactif dans une chaîne latérale et/ou une huile de silicone de type diol monoterminal (a2).
(JA)
軸体2の外周面に形成された弾性層3と、弾性層3の外周面に形成された被覆層4とを備える現像ローラ1であって、被覆層4が、(a)ポリオール、(b)イソシアネート、(c)表面粗さ材、及び(d)導電材を含有する被覆層用樹脂組成物を熱硬化させてなり、(a)ポリオールが、(a1)側鎖に未反応性シリコーン基を有するポリオール、及び(a2)片末端ジオール型シリコーンオイルの少なくとも1種を含有する現像ローラ1とする。
