Abstract: The amount of a paint for forming a porous heat-resistant layer supplied to the outer surface of a gravure roll is adjusted by removing the paint with a blade that is disposed so as to contact the outer surface. A resin blade is used, and the position at which the resin blade contacts the outer surface of the gravure roll is changed as the resin blade wears away. This prevents the amount of the paint for forming the porous heat-resistant layer removed from the outer surface of the gravure roll from changing as the resin blade wears away, so that the excess amount of the paint carried on the outer surface of the gravure roll is removed with good accuracy. An almost constant amount of the paint is thus transferred to an electrode surface from the outer surface of the gravure roll, and a porous heat-resistant layer with an almost uniform thickness is stably formed on an industrial scale.
