An image recording apparatus includes an ejecting head which ejects photocurable liquid onto the recording medium; and a light irradiator which radiates the light to the liquid which is ejected onto the recording medium, in which the light irradiator includes a light source substrate which is arranged so as to face the recording medium, and includes a light source which radiates the light to the recording medium; a heat transport member which includes a portion to be connected which is in thermal contact with the light source substrate, and a portion to be cooled which is located at a position which is further separated from the light source substrate than the portion to be connected, and transports heat from the portion to be connected to the portion to be cooled; and a cooling fan which cools down the portion to be cooled.
