A fluororesin powder fluidized bed is formed in a container containing fluororesin powder on the surface of an elastic layer formed by a conventional method such as casting, and a negative charge of 10 to 5 okv is applied to the fluororesin powder, and static electricity is applied to the fluororesin powder. The fluororesin-coated roller of the present invention is obtained by electrostatically powder coating the fluororesin with a removal device so that the negative charge is reduced to about -500 nV using a gun, and then melting and baking it.
