Abstract:
1. A method for producing a heat-resistant resin endless belt, comprising the steps of: 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, the first inclined thinned portion and the second inclined thinned portion being tapered toward the end of the first surface and the end of the second surface, respectively, the end of the first surface being opposite to the end of the second surface; obtaining an adhesive composition wherein an additive polymerized silicon adhesive composition containing ferric (III) oxide in powder form is compounded with an additive polymerized silicon adhesive composition containing no ferric (III) oxide such that the ferric (III) oxide is between 6.5 and 9.9 weight % of a solid content of the obtained adhesive composition; applying the 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, wherein 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.
