Abstract
A recording apparatus having a black ink recording head for discharging black ink onto a recording material and at least one single color non-black recording head for discharging non-black ink onto the recording material includes a recording head driver for driving the recording heads to discharge the ink onto the recording material; and a controller for controlling the recording head driver so that a volume, per unit area of the recording material, of the black ink discharged from the blue ink recording head and deposited on the recording region of the recording material is larger than that of the non-black ink discharged from the non-black ink recording head and deposited on the recording region of the recording material.
