## Abstract

An ink jet recording apparatus includes a printer head that ejects ink and a platen. The ink includes an organic solvent, a surfactant, and 60% by mass or less of water. The platen is composed of a material containing a conductive resin. A solubility parameter A [(J/cm3)1/2] calculated from the organic solvent and the surfactant and a solubility parameter B [(J/cm3)1/2] of the conductive resin satisfy |A−B|≧2.

## Claims

### Claim 1

An ink jet recording apparatus comprising:
a printer head that ejects ink; and
a platen,
the ink including an organic solvent, a surfactant, and 60% by mass or less of water,
the platen being composed of a material containing a conductive resin,
wherein a solubility parameter A [(J/cm3)1/2] calculated from the organic solvent and the surfactant and a solubility parameter B [(J/cm3)1/2] of the conductive resin satisfy |A−B|≧2.

### Claim 2 (depends on 1)

The ink jet recording apparatus according to claim 1, wherein a conductivity of the conductive resin is 106 Ω·cm or more and 1012 Ω·cm or less.

### Claim 3 (depends on 1)
