PROBLEM TO BE SOLVED: To provide a method for manufacturing an OA roller such as a developing roller and a transfer roller, capable of uniformly forming a coated film without causing bubbles in the coated film, a locally formed film and liquid- gathering in the case of forming the coated film on the surface of a substrate by dipping the substrate into coatings. SOLUTION: As for the method for manufacturing the developing roller, etc., including a process of forming the coated film on the substrate surface of the roller 1 by dipping the substrate of the roller 1 into the coatings, the temperatures of the substrates of many rollers 1 suspended by a hanger 2 are maintained so as to be nearly uniform in the entire roller 1 before the rollers are dipped. |
