摘要

PROBLEM TO BE SOLVED: To provide a coating device for a resin dispersion liquid capable of forming a smooth coating film even if a core body with bad roundness is used when helical winding coating is carried out and a coating method, and to further provide a manufacturing method for a polyimide endless belt and a fixing belt utilizing the coating method for the resin dispersion liquid.;SOLUTION: In the coating method for coating the core body 10 with a polyimide precursor solution 14 by rotating the cylindrical core body 10 such that a central axis becomes horizontal, flattening deposited polyimide precursor solution 14 while flowing down and depositing, for example, the polyimide precursor solution 14 (resin dispersion liquid) on the core body 10 and relatively and horizontally moving the deposition part and the flattened part from one end of the core body 10 to the other end, a flattening device 24 for flattening is constituted by a spatula 24 (plate-like member) press-contacted with the core body 10; and an adjustment member 26 for adjusting the press-contact force of the spatula 24 to the core body 10.;COPYRIGHT: (C)2005,JPO&NCIPI
