Wiper blade member for ink jet recording head, ink jet recording apparatus having wiper blade and ink jet recording method

Abstract

The invention provides a wiper blade member maintaining a high water repellency even for a pigment ink, and an ink jet recording apparatus equipped with such wiper blade member. The wiper blade member of the invention for eliminating a deposition an ink discharge face of the ink jet recording head is made water repellent by a condensate of a fluorine-containing hydrolysable compound. The condensate increases a fluorine content significant and shows a strong adhesion a substrate (blade) by the presence of the hydrolysable group. It strongly adhered to the substrate by a condensation reaction only by a hydrolysis, but the adhesion can be further improved by a photo- or thermocuring. The curing reaction can be executed at a relatively low temperature, without causing a damage to the blade constituting the substrate.
