ABSTRACT:
In order to realize stable rocking operation of the armature and further obtain magnetic characteristics required for high-speed printing, the magnetic circuit forming member formed of magnetic material like a plate and having the through hole in the direction of thickness thereof is stacked in two or more layers in the direction of thickness, pressure is applied to the two or more stacked magnetic circuit forming members in the stacking direction to make the magnetic circuit forming members adhere to each other, and the two or more magnetic circuit forming members put in the adhering state are subjected to nitriding.
