A carrier vapor diluting unit of a liquid printer dilutes and exhausts carrier
vapor generated in a fusing apparatus. The unit includes a housing to surround
the thermal roller and the pressing roller, a duct which is connected to an inside
and an outside of the housing and forms a path through which a mixed gas in which
the carrier vapor is mixed with the air is drawn and exhausted, and a fan which
forcibly transfers the mixed gas via the duct.
