Belt member, fixing device, and image forming apparatus |
摘要 |
Disclosed are a belt member having high wear resistance and thereby capable of maintaining its initial surface properties for a long period of time and a fixing device provided with, the belt member, and an image forming apparatus. The belt member has a belt shape, and its surface is formed of a cured resin including a structural unit derived from urethane (meth)acrylate (A) having at least three (meth)acryloyloxy groups per molecule, a structural unit derived from a polyfunctional monomer (B) having no urethane bond and having at least three (meth)acryloyloxy groups per molecule, and a structural unit derived from a fluorine-modified acrylate (C). The cured resin contains 18 to 63% by mass of the structural unit derived from the urethane(meth)acrylate (A), 18 to 63% by mass of the structural unit derived from the polyfunctional monomer (B), and 10 to 40% by mass of the structural unit derived from the fluorine-modified acrylate(C). |

1. A belt member included in an electrophotographic image forming apparatus, the belt member comprising:
a surface formed of a cured resin including a structural, unit derived from urethane (meth)acrylate (A) having at least three (meth)acryloyloxy groups per molecule, a structural unit derived from a polyfunctional monomer (B) having no urethane bond and having at least three (meth)acryloyloxy groups per molecule, and a structural, unit derived from a fluorine-modified acrylate (C), wherein the cured resin contains 18 to 63% by mass of the structural unit derived from the urethane(meth)acrylate (A), 18 to 63% by mass of the structural unit derived from the polyfunctional monomer (B), and 10 to 40% by mass of the structural unit derived from the fluorine-modified acrylate (C). |
