ABSTRACT:
An ink-jet print head comprises a plurality of heater boards as unit substrates which are connected to each other and each of which has a plurality of discharge elements arranged therein so that the nonuniformity of density which would ordinarily be produced in portions of the image printed by the head corresponding to boundaries between the respective heater boards is decreased. Since a plurality of ink-jet heads are disposed so that the boundaries between respective heater boards of the heads do not overlap one another, the potential nonuniformity of density at the boundaries can be decreased by interrelation between the heads.
