    • PROBLEM TO BE SOLVED: To solve a problem that coating becomes uneven when carrying out ring coating to a roller in which outer diameter changes.SOLUTION: The method for manufacturing the roller member uses a coating device for forming a coating film on the outer peripheral surface of the shaft body by discharging coating liquid from the discharge opening 28 of a ring coating head while relatively moving the shaft body which is supported in a vertical direction and in which the outer diameter changes in an axial direction and the ring coating head surrounding all the outer peripheral surface of the shaft body and arranged at a predetermined distance from the center axis of the shaft body in the axial direction. The ring coating head has an inner diameter changeable member 23 capable of changing the inner diameter below the discharge opening 28. The inner diameter Dof the inner diameter changeable member 23 is changed such that a changing quantity of the inner diameter Dof the inner diameter changeable member 23 becomes substantially equal to the changing quantity of the outer diameter Dof the shaft body changing in the axial direction. By changing thus, the difference between the inner diameter Dof the inner diameter changeable member 23 and the outer diameter Dof the shaft body can be kept substantially constant even during relatively moving the shaft body and the ring coating head in the axial direction.
