Drying apparatus and printing apparatus

A drying apparatus for drying ink adhering to a print medium, the drying apparatus comprising:

• a heater facing a transportation path where the print medium is transported;
• a blowing source configured to blow air to the heater;
• and
• a casing configured to enclose the heater, the casing comprising:
• an inflow port into which the air from the blowing source flows;
• and
• a blowing port configured to narrow and blow warm air heated with the heater to the transportation path outside the casing in a direction along the transportation path;
• an exhaust unit disposed outside the casing and configured to exhaust the warm air blown through the blowing port to the transportation path;
• a suction unit configured to supply air to the blowing source;
• and
• a warm-air circulator configured to supply the warm air collected in the exhaust unit to the suction unit, the suction unit comprising:
• an outside-air suction port configured to suck outside air;
• a warm-air suction port provided as the exhaust unit and the warm-air circulator on a path connecting the blowing source and the outside-air suction port, and configured to suck the warm air blown to the transportation path;
• and
• a suction-blowing source provided on the path adjacent to the outside-air suction port rather than the warm-air suction port, and configured to suck the outside air, wherein
• the suction-blowing source is set to blow a smaller quantity of air than the blowing source.
