ABSTRACT:
Even in the case where preliminary ejection is performed by a recording head having an array of pigment ink ejection outlets and an array of dye ink ejection outlets in which a length of the pigment ink ejection outlet array is longer than a length of the dye ink ejection outlet array, deposition of preliminarily ejected pigment ink at a preliminary ejection receiving portion is effectively prevented by providing an inclined surface at the preliminary ejection receiving portion so that ink from the dye ink ejection outlets is received at an upstream position of the inclined surface and ink from the pigment ink ejection outlets is received at a downstream position of the inclined surface in a direction of gravity.
