PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus and a method capable of decreasing granular feeling of low density parts and decreasing the amount of ink feeding on a Dmax part. SOLUTION: The inkjet recording apparatus of the present invention is characterized in that a first delivering means for delivering a first ink with a relatively low coloring material density among a plurality of inks being the same color type and with different coloring material densities, and a second delivering means for delivering a second ink with a relatively higher coloring material density than the first ink among a plurality of the inks being the same color type and with different coloring material densities, are provided, and a first dot diameter hit from the first delivering means is smaller than a second dot diameter hit from the second delivering means. In addition, the coloring material density of the second ink is 6-20 mass%, and the coloring material density of the first ink is 1-5 mass%, and the dot sizes are controlled by physical properties (surface tension, contact angle and viscosity) of the inks.
