The driving signal generation section is able to generate a first ejection drive pulse for ejecting the first liquid and a second ejection drive pulse for ejecting the second liquid. The control section forms a pre-dot group in advance on a landing target area of the first liquid in the ejection target by ejecting the second liquid on the basis of the second ejection drive pulse, and subsequently forms a pattern dot on the landing target area, on which the pre-dot group is formed, by ejecting the first liquid on the basis of the first ejection drive pulse. In the apparatus, a total length of the pre-dot group in a direction of the relative movement is longer than a total length of the pattern dot in the direction of the relative movement.
