Title (EN) ENDLESS BELT
(FR) COURROIE SANS FIN
(JA) 無端ベルト
Abstract:
(EN) Provided is an endless belt (1) capable of suppressing surface cracks due to ozone deterioration and belt-set creases. The endless belt (1) is used in an electrophotographic image-forming device. The endless belt (1) comprises a tubular base layer (2) and an elastic layer (3) laminated on an outer periphery of the base layer (2). The elastic layer (3) comprises a cured material of a composition containing polycarbonate polyol, polyisocyanate, and a rubber polymer including a double bond. The mass ratio of the polycarbonate polyol and the rubber polymer in the composition can be set in a range of 5:95-95:5. The rubber polymer can include at least one of an acrylonitrile-butadiene rubber and an epichlorohydrin rubber.
(FR) L'invention concerne une courroie sans fin (1) susceptible de supprimer des fissures de surface dues à la dégradation par l'ozone et des plis sur la courroie. La courroie sans fin (1) est utilisée dans un dispositif de formation d'images électrophotographiques. La courroie sans fin (1) comprend une couche de base tubulaire (2) et une couche élastique (3) stratifiée sur une périphérie externe de la couche de base (2). La couche élastique (3) comprend un matériau durci d'une composition contenant du polyol de polycarbonate, du polyisocyanate et un polymère de caoutchouc comprenant une liaison double. Le rapport massique du polyol de polycarbonate et du polymère de caoutchouc dans la composition peut être défini dans une plage de 5:95 à 95:5. Le polymère de caoutchouc peut comprendre un caoutchouc acrylonitrile-butadiène et/ou un caoutchouc d'épichlorhydrine.
(JA) オゾン劣化による表面クラック、および、ベルトセット癖を抑制することが可能な無端ベルト(1)を提供する。無端ベルト(1)は、電子写真方式の画像形成装置に用いられる。無端ベルト(1)は、筒状の基層(2)と、基層(2)の外周に積層された弾性層(3)とを有している。弾性層(3)は、ポリカーボネートポリオールと、ポリイソシアネートと、二重結合を含むゴムポリマーとを含有する組成物の硬化物よりなる。組成物におけるポリカーボネートポリオールとゴムポリマーとの質量比は5:95~95:5の範囲内とすることができる。ゴムポリマーは、アクリロニトリル-ブタジエンゴムおよびエピクロルヒドリンゴムの少なくとも一つを含んでいるとよい。
