Claim Text:
1. An image recording apparatus comprising: a supporting member having a curved surface, the supporting member configured to transport a recording medium in a transport direction while supporting the recording medium with the curved surface; a head having a nozzle surface having a plurality of nozzles arranged with a certain nozzle pitch and for discharging a radiation-curable ink, the head configured to discharge the radiation-curable ink from the nozzles to the recording medium supported by the curved surface so that the radiation-curable ink forms ink dots; a first irradiation unit configured to irradiate the ink dots with first radiation at a first irradiation point, the first irradiation point located downstream of a dot formation point at which the ink dots are formed by discharging the radiation-curable ink onto the recording medium; and a control section configured to control a transportation speed of the recording medium transported by the supporting member, the first irradiation unit having a light source configured to generate the first radiation, the first irradiation unit located in a position downstream of the head where the first radiation does not reach the nozzle surface directly and where reflected radiation of the first radiation that is reflected by the supporting member and the recording medium supported by the curved surface does not reach the nozzle surface, wherein a time period from a time immediately after the radiation-curable ink is discharged onto the recording medium to a time when a diameter of the ink dots reaches twice the nozzle pitch is defined as a first time period, the control section configured to control the transportation speed in such a manner that the ink dots formed at the dot formation point move to the first irradiation point in a second time period equal to or shorter than the first time period.
