To provide an ink jet recording device and an ink jet recording method for effectively suppressing the occurrence of an imaging failure due to the deposition of ink discharged to a recording medium on a carrying roller even when performing high-speed image formation.

The ink jet recording device and the ink jet recording method use an ink jet head to perform image formation on the recording medium. Herein, the carrying roller is provided for carrying the recording medium in contact with its ink-discharged recording surface. The surface of the carrying roller is subjected to treatment with fullerene and its derivative or either one of them.
