Abstract
An inkjet printer employing an ink circulation system includes an ink temperature adjusting unit configured to adjust temperatures of circulating ink. The ink temperature adjusting unit includes: a first temperature-adjusting path for cooling ink connected to a first ink circulation path and a second ink circulation path; and a second temperature-adjusting path for heating ink connected to the second ink circulation path separately from the first temperature-adjusting path, connected to the first ink circulation path while joining the first temperature-adjusting path, and having a larger flow path resistance than that of the first temperature-adjusting path at least on a side near the first ink circulation path.
