An inkjet printer (1), comprising: a recording part (2) for ejecting droplets of ink from an outlet toward an object (9), to form dots on said object (9); a moving mechanism (3) for moving said object (9) relatively to said recording part (2) in a moving direction; and a controller (4) for sequentially inputting signals to said recording part (2) said signals being instructions for ejection of droplets, in parallel with movement of said object (9) relative to said recording part (2), wherein said recording part (2) includes: a first ejecting part (23) which ejects ink in a first color and is capable of forming dots of m or more different sizes, m being an integer equal to or more than two; and a second ejecting part (23) which ejects ink in a second color different from said first color, and is capable of forming dots of said m or more different sizes, characterized in that said first ejecting part (23) forms dots of said m different sizes and said second ejecting part (23) forms dots of n different sizes included in said m different sizes, n being an integer equal to or more than one and smaller than m, and a driving signal used for forming a dot of at least one size included in said n sizes by said first ejecting part and a driving signal used for forming a dot of said at least one size by said second ejecting part are different from each other. |
