Abstract
A wiper blade member can maintain a high water repellency even for a pigment ink. The wiper blade member, which can eliminate a deposit on an ink discharge face of an ink jet recording head, is made water repellent by a condensate of a fluorine-containing hydrolysable compound. The condensate increases a fluorine content significantly and shows a strong adhesion to a substrate (blade) by the presence of the hydrolysable group. The condensate strongly adheres to the substrate by a condensation reaction only by hydrolysis, but the adhesion can be further improved by photo- or thermocuring. The curing reaction can be executed at a relatively low temperature, without causing damage to the blade constituting the substrate.
