Abstract

The doctor blade consists of at least a substrate provided with an element having a face adapted for working with a magnetic roller, said element being made at least partly of an elastic material, wherein the face adapted for working with a magnetic roller has an abrasion resistance of less than 0.5g (measured according to the method ASTM D4060), and a shore hardness of less than 100.
