<p>PURPOSE:To prevent an offset over the entire surface with a small amount of a liquid by performing uniform and even application, by providing a fixing roller, equipped with a means of applying an offset preventing liquid, with a means of applying a surface active agent. CONSTITUTION:Felt, paper, nonwoven cloth, woven cloth, etc., is impregnated with a liquid and coating member 8 made of a material permeable to the impregnated liquid is brought into contact with roller 1 pressing the unfixed toner image support surface of toner image support material S. This coating member 8 is impregnated with a liquid obtained by uniformly mixing silicone oil as an offset preventing liquid and polyethylene glycol ester, for example, as a surface active agent. Consequently, a small amount of silicone oil enough to prevent offsetting sufficiently through the operation of the surface active agent can be applied uniformly onto the surface of fixing roller 1.</p> |
