1. An after-treatment unit comprising:
a post processing section that is configured to execute post-processing on a medium after a recording section applies a liquid to the medium to thereby perform a recording on the medium,
a drying unit configured to contact the medium and perform drying of the liquid on the medium after the recording by heating the medium to avoid jamming, which is caused when the medium is curled; and
a control unit configured to control operation of the drying unit,
wherein the drying unit is configured such that a heating region is divided into a central subdivision region and non-central subdivision regions in a width direction which intersects a medium transport direction and to be capable of individually modifying a heating state for each subdivision region according to a width size of the medium,
wherein the drying unit is configured to include a roller pair of a first roller and a second roller, wherein the roller pair pinches the medium between the first roller and the second roller,
wherein at least the first roller is heated,
wherein the first roller has a plurality of heat sources in the width direction which intersects the medium transport direction, and
wherein the control unit is configured to adjust a power of each heat source individually such that a heat state of the central subdivision region and a heat state of the non-central subdivision regions are different from each other according to the width size of the medium.
