PROBLEM TO BE SOLVED: To provide a coating roller capable of stably coating unstabilizing liquid required for reproduction of a transfer paper onto the transfer roller, even in the case of making peripheral speed equal to the transporting speed the transfer paper, and a tool suitable for manufacturing the same. SOLUTION: The coating roller is constituted that mutually independent numbers of concave parts 23a is severally disposed, on periphery of the coating roller 23 coating the unstabilinzing liquid to the transfer paper on the surface of which the toner image is formed, in order to change a sticking state in between toner and the transfer paper to the unstable state. The respective concave parts 23a is, possible to be formed, by pressing the rotary tool composed of the roller member consisting of a material harder than the surface part of the coating roller 23, and provided with projecting parts respectively engaged to the concave parts 23a in a desired shape on its periphery of the coating roller 23, onto a base stock of the coating roller. Moreover, the projecting parts of the rotary tool, may be provided so that the periphery of the roller member remains. |
