A liquid ejection apparatus comprising: at least one head (10;40) each having an ejection face (10a;40a) which has a plurality of ejection openings opened therein for ejecting liquid onto a recording medium; a convey belt which has a support region and at least one preliminary ejection region each provided on a face of the convey belt and which is configured to convey the recording medium in a conveying direction parallel to the ejection face by moving the face of the convey belt in a state in which the face faces the ejection face, wherein the support region is a region for supporting the recording medium, wherein the preliminary ejection region is a region onto which the liquid is ejected from the ejection openings in preliminary ejection, and wherein the preliminary ejection is ejection not contributing to image recording; and a controller configured to control the head and the convey belt, the liquid ejection apparatus being characterized in that: the liquid includes recording liquid; and the controller is configured to control the head and the convey belt on the basis of preliminary ejection data for the preliminary ejection such that until a specific length of time has passed from the ejection of the liquid from the ejection openings onto the preliminary ejection region, the head ejects the recording liquid onto the preliminary ejection region a predetermined number of times successively such that droplets of the recording liquid ejected from the head are respectively landed on positions that do not overlap. at least one head (10;40) each having an ejection face (10a;40a) which has a plurality of ejection openings opened therein for ejecting liquid onto a recording medium; a convey belt which has a support region and at least one preliminary ejection region each provided on a face of the convey belt and which is configured to convey the recording medium in a conveying direction parallel to the ejection face by moving the face of the convey belt in a state in which the face faces the ejection face, wherein the support region is a region for supporting the recording medium, wherein the preliminary ejection region is a region onto which the liquid is ejected from the ejection openings in preliminary ejection, and wherein the preliminary ejection is ejection not contributing to image recording; and a controller configured to control the head and the convey belt, the liquid ejection apparatus being characterized in that: the liquid includes recording liquid; and the controller is configured to control the head and the convey belt on the basis of preliminary ejection data for the preliminary ejection such that until a specific length of time has passed from the ejection of the liquid from the ejection openings onto the preliminary ejection region, the head ejects the recording liquid onto the preliminary ejection region a predetermined number of times successively such that droplets of the recording liquid ejected from the head are respectively landed on positions that do not overlap. the liquid includes recording liquid; and the controller is configured to control the head and the convey belt on the basis of preliminary ejection data for the preliminary ejection such that until a specific length of time has passed from the ejection of the liquid from the ejection openings onto the preliminary ejection region, the head ejects the recording liquid onto the preliminary ejection region a predetermined number of times successively such that droplets of the recording liquid ejected from the head are respectively landed on positions that do not overlap.
