This image recording apparatus includes a viscosity increasing light irradiator that increases the viscosity of ink ejected onto a recording medium, and a fixing light irradiator that fixes the ink on the recording medium. The fixing light irradiator is disposed behind a first switching part that causes the transport orientation of the recording medium to approach the vertical. This reduces the footprint of the image recording apparatus. Also a second type of irradiation light emitted from the fixing light irradiator is intercepted by the recording medium. This suppresses the unwanted curing of the ink in an image recorder. Also the viscosity increasing light irradiator is disposed at a location upstream from the first switching part in a transport direction. This suppresses the decrease in printing quality resulting from the passage of the ink remaining uncured through the first switching part.
