Abstract
An inkjet recording head characterized by better ink repellency, greater resistance to abrasion and a longer service life than a conventional product can be attained when an ink repellent layer comprising a compound made up of a perfluoropolyether chain and alkoxysilane residue is formed on the nozzle plate of the inkjet recording head. An inkjet printer for forming an image by jetting out liquid ink, wherein this nozzle plate is employed, becomes substantially maintenance free.
