Abstract
A method for producing a heat-resistant resin endless belt includes preparing a heat-resistant resin sheet including a first surface and a second surface opposite to each other; forming a first inclined thinned portion at an end of the first surface and a second inclined thinned portion at an end of the second surface as the inclined thinned portion is formed to be gradually thinned toward the end, the end of the first surface being opposite to the end of the second surface; applying an adhesive composition by a screen printing method on at least one of the first and second inclined thinned portions; joining the first and second inclined thinned portions of the sheet to each other; and hardening the adhesive composition, in which the adhesive composition is an additive polymerized silicon adhesive composition containing ferric (III) oxide at between 6.5 and 9.9 weight % of a solid content of the adhesive composition; a viscosity of the additive polymerized silicon adhesive composition before being hardened at 23° C. is between 50 and 100 Pa s; and an expanding rate at shearing of the adhesive composition after being hardened is 250% or more on a tensile shear test.
