Abstract

A developing unit using a high concentration ink includes a developing solution supply unit supplying the developing solution containing the high concentration ink, a developing roller, whose lower half is soaked in the developing solution of the developing solution supply unit, absorbing the developing solution by a surface tension, and a photosensitive drum contacting the developing roller, receiving the developing solution absorbed on a surface of the developing roller and developing a latent electrostatic image formed on a surface of the photosensitive drum. Accordingly, as much as about 100% of a binary ink development (BID) is achieved, thereby providing a high quality image.
