Drying device and printing apparatus

A printing apparatus comprising:

• a liquid applicator to apply liquid onto a surface of a web;
• a drum to heat the web that is wound around the drum and applied with the liquid by the liquid applicator;
• a first conveyance path defining a route on which the web passes from the liquid applicator to a web-winding start position of the drum at which the web starts winding the drum;
• a second conveyance path defining a route on which the web passes from a web-detaching position of the drum at which the web detaches from the drum to a downstream side in the conveyance direction;
• and
• a heater to heat the web in at least one of the first conveyance path and the second conveyance path,
• the first conveyance path and the drum being disposed so that a liquid applied surface of the web on which the liquid is applied by the liquid applicator has a convex shape.

A drying device comprising:

• a drum to heat a web wound around the drum and applied with liquid;
• a first conveyance path defining a route on which the web passes from an upstream side in a conveyance direction to a web-winding start position of the drum at which the web starts winding the drum;
• a second conveyance path defining a route on which the web passes from a web-detaching position of the drum at which the web detaches from the drum to a downstream side in the conveyance direction;
• and
• a heater to heat the web in at least one of the first conveyance path and the second conveyance path,
• the drum, the first conveyance path, and the second conveyance path being disposed in a normal direction of an outer circumference of the drum in at least one of an order of the drum, the first conveyance path, and the second conveyance path and an order of the drum, the second conveyance path, and the first conveyance path.

A drying device comprising:

• a first rotator to heat a web wound around the first rotator and applied with liquid;
• a second rotator to heat the web wound around the second rotator and applied with the liquid;
• a first conveyance path defining a route on which the web passes from an upstream side in a conveyance direction to a web-winding start position of the first rotator;
• a second conveyance path defining a route on which the web passes from a web-detaching position of the first rotator to a web-winding start position of the second rotator;
• a third conveyance path defining a route on which the web passes from a web-detaching position of the second rotator to a downstream side in the conveyance direction;
• and
• a heater to heat the web in at least one of the first conveyance path and the third conveyance path.
