Claim:
1. A process for manufacturing an elastic roller, the elastic roller having a mandrel and a coating film on an outer peripheral surface thereof, the process comprising: a first step of forming a coating film of a coating material on an outer peripheral surface of a first mandrel by a circular coating head; and a second step of forming a coating film of the coating material on an outer peripheral surface of a second mandrel by the circular coating head, the circular coating head having: the first step including: arranging the first mandrel approximately coaxially with a central axis of the circular coating head; and forming the coating film of the coating material on the outer peripheral surface of the first mandrel by relatively moving the circular coating head and the first mandrel so that the inclined surface of the coating head is positioned in a downstream side, while ejecting the coating material from the circular slit; and the second step including: arranging the second mandrel approximately coaxially with the central axis of the circular coating head; and forming the coating film of the coating material on the outer peripheral surface of the second mandrel by relatively moving the circular coating head and the second mandrel so that the inclined surface of the coating head is positioned in the downstream side, while ejecting the coating material from the circular slit, wherein the process further comprises a cleaning step between the first step and the second step, the cleaning step comprising:
