Printing apparatus

1. A printing apparatus comprising:

a printing section that performs printing by adhering an ink to a medium;

a transport section that transports the medium along a transport path of the medium; and

a heating device that heats the medium, on which printing is finished,

wherein a region between the transport path and the heating device is set as a heating region,

wherein the heating device includes an infrared ray emission section which has an infrared ray emission surface that faces the transport path via the heating region, and a heating section which heats the infrared ray emission section,

wherein at least a portion of the infrared emission section includes at least a first partitioning wall formed in a zig-zag shape, the first partitioning wall including flow outlets for providing hot air heated by the heating section to the heating region, the first partitioning wall comprising intersecting walls meeting at an apex with the flow path outlets spaced from the apex,

wherein the first partitioning wall includes an aluminum alloy and an oxide layer formed on a surface of the aluminum alloy, wherein the aluminum alloy contains Aluminum (Al) and 0.3 wt % to 4.3 wt % of manganese (Mn), wherein the Mn and Al intermetallic compound is precipitated,

wherein the heating device includes a portion configured to cool the medium at a position downstream of the heating region, and

an area of the infrared ray emission surface is greater than a projection area obtained by projecting the infrared ray emission surface toward the transport path.

2. The printing apparatus according to claim 1 , wherein,

the heating device includes

a heating chamber, at least a part of which is partitioned by the first partitioning wall and a second partitioning wall, through which an inlet is formed penetrating therethrough, and

a gas inflow section that causes a gas to flow into the heating chamber via the inlet, and

the heating section heats the heating chamber.

3. The printing apparatus according to claim 2 , further comprising:

a support member that supports the medium, configures at least a part of the transport path, and is provided to face the heating device via the heating region,

wherein the first partitioning wall includes the intersecting walls that extend in a direction that intersects the medium supported on the support member, and

wherein the outlet is formed penetrating through the intersecting wall in a thickness direction thereof.

4. The printing apparatus according to claim 2 ,

wherein the gas inflow section causes a gas that is taken in from the heating region to flow into the heating chamber.
