## Abstract

A recording device including an intermediate transfer unit; a supply unit that supplies ink receiving particles that receive an ink onto the intermediate transfer unit in the form of a layer; a particle density increasing unit that increases the particle density of the layer of the ink receiving particles supplied onto the intermediate transfer unit; an ink application unit that applies an ink to the layer of the ink receiving particles supplied onto the intermediate transfer unit; a transfer unit that transfers the layer of the ink receiving particles onto a recording medium; and a fixing unit that fixes the layer of the ink receiving particles transferred onto the recording medium.

## Claims

### Claim 1
