Claim:
A method of forming a seamless belt suitable for use with an image forming system, comprising: flow coating a composition of a polyimide, a phosphate ester internal release agent, and a solvent onto and directly contacting an outer surface of a rotating substrate; partially curing the coating at a temperature of from about 125° C. to about 190° C. for a time of from about 30 to about 90 minutes to form a seamless belt; removing the partially cured belt by self-releasing the partially cured belt from the rotating substrate; and tensioning and rotating the partially cured belt between two rollers applying a tension of from about 1 kg to about 10 kg while fully curing the partially cured belt at a temperature of from about 250° C. to about 370° C. for a time of from about 30 to about 90 minutes.
