<P>PROBLEM TO BE SOLVED: To provide an endless belt for an electrophotographic apparatus that has high adhesiveness in the boundary between a base layer and a front surface and high durability, and to provide an excellent image. <P>SOLUTION: In the endless belt for the electrophotographic apparatus, the front layer 2 is formed on the outer peripheral surface of the base layer 1. The base layer 1 is formed of a hardening object of a resin composition that contains (A)-(C) components and where an NCO index is set in a range of 90-95. The front layer 2 is formed of a hardening object of a resin composition that contains (D) and (E) components and where the NCO index is set in a range of 125-500. Here, (A) is aromatic diisocyanate, (B) is the anhydride of an aromatic polycarboxylic acid, (C) is diol or a dicarboxylic acid, (D) is an isocyanate compound, and (E) is fluororesin having a functional group reacting with an isocyanate group of the (D) component. <P>COPYRIGHT: (C)2010,JPO&INPIT |
