METHOD FOR FORMING COATING FILM AND METHOD FOR PRODUCING FIXING MEMBER

摘要

The method for forming a coating film includes: supplying a first liquid from a nozzle to a cylindrical substrate to thereby form the coating film of the first liquid, wherein the method includes, pressing a member including a second liquid, to form a liquid film of the second liquid on the peripheral surface, and forming the coating film of the first liquid includes: supplying the first liquid onto the liquid film of the second liquid formed on the peripheral surface of the substrate to form a bead of the first liquid between the liquid-supplying unit and the liquid film of the second liquid, and extending the bead in a circumferential direction of the substrate.

1. A method for forming a coating film on a peripheral surface of a cylindrical or columnar substrate, comprising:
a first liquid coating film forming step comprising: supplying a first liquid from a nozzle to the peripheral surface of the substrate that relatively rotates against the nozzle, while relatively moving the nozzle and the substrate in an axial direction of the substrate, and forming a first liquid coating film on the peripheral surface of the substrate; and a step of forming a liquid film of a second liquid on the peripheral surface of the substrate, prior to supplying the first liquid to the peripheral surface of the substrate, by pressing a member comprising the second liquid, on the peripheral surface of the substrate, while relatively rotating the member and the substrate, and relatively moving the member and the substrate in an axial direction of the substrate, and forming a liquid film of the second liquid on the peripheral surface of the substrate, the second liquid being the same as the first liquid or having a high affinity with the first liquid, wherein, in the first liquid coating film forming step, the first liquid is supplied onto the liquid film of the second liquid before drying the liquid film of the second liquid, and wherein: the first liquid coating film forming step further comprises the steps of: forming a bead of the first liquid between the nozzle and the liquid film of the second liquid, and extending the bead in a circumferential direction of the substrate.
