Abstract
There are provided an endless belt having a structure containing at least three layers, a middle layer being disposed between the outermost layer and a bottom layer, and the middle layer being composed of a material having a thermal decomposition temperature lower than the deposition temperature of each of the outermost layer and the bottom layer, and provided a method for manufacturing the endless belt. There are provided an endless belt having high surface resistivity, an excellent toner releasing property, an excellent non-contaminated property, stable volume resistivity, excellent adhesion between a surface layer and an elastic layer, and the like without the occurrence of disadvantageous bleeding of a contaminant, and a method for manufacturing the endless belt.

A method for manufacturing an endless belt having a structure containing at least three layers, a middle layer being disposed between the outermost layer and a bottom layer, and the middle layer being composed of a material having a thermal decomposition temperature lower than the deposition temperature of each of the outermost layer and the bottom layer, the method comprising:
- a disposing step of fixing the outermost layer to the inner side of a rigid body and disposing the middle layer and the bottom layer in that order, the middle layer being opposite the bottom layer;
- and
- an expansion pressurizing step of pressing the bottom layer from the inside of the bottom layer toward the outermost layer to form an endless belt having at least three layers.
