Transport device, drying device, and printing apparatus

A transport device which transports a web-shaped substrate from a first atmosphere of a first atmosphere temperature to a second atmosphere of a second atmosphere temperature different from the first atmosphere temperature along a transport path, the transport device comprising:

• a plurality of pass rollers that are disposed in the transport path and that each support the substrate;
• a plurality of heaters that heat the plurality of pass rollers respectively;
• a memory that stores a command that a processor executes;
• the processor that executes the command stored in the memory;
• and
• a thermometer that measures a surface temperature of the substrate,
• wherein the processor controls the heater based on a measurement result of the thermometer to adjust a surface temperature of the pass roller,
• wherein the plurality of heaters perform heating such that the closer a pass roller is to an upstream side of the transport path, the closer a temperature to which the pass roller is heated is to the first atmosphere temperature and the closer a pass roller is to a downstream side of the transport path, the closer a temperature to which the pass roller is heated is to the second atmosphere temperature, and
• wherein the processor controls the heater based on a difference between an amount of expansion of the substrate at the surface temperature of the substrate and an amount of expansion of the substrate at the surface temperature of the pass roller to adjust the surface temperature of the pass roller.
