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.
Claims21
A developing unit comprising:
- a developing solution supply unit containing a developing solution of a concentration of ink particles;
- a developing roller having a portion immersed in the developing solution of the developing solution supply unit, absorbing the developing solution by a surface tension between the developing solution and the portion of the developing roller immersed in the developing solution of the developing solution supply unit;
- and
- a photosensitive drum contacting the developing roller, receiving the developing solution deposited on the surface of the developing roller, and developing a latent electrostatic image formed on a surface of the photosensitive drum with the received developing solution.
A developing unit comprising:
- a developing solution supply unit containing a developing solution;
- a developing roller having a surface tension formed between the developing solution and the developing roller and absorbing the developing solution by the surface tension to form an ink film having the same concentration as the developing solution on a surface of the developing roller;
- and
- a photosensitive drum having a latent electrostatic image, contacting the developing roller to receive the ink film from the developing roller, and developing the latent electrostatic image with the received ink film of the developing solution.
A developing unit comprising:
- a developing solution supply unit containing a developing solution;
- a photosensitive drum having a latent electrostatic image;
- and
- a developing roller disposed between the developing solution supply unit and the photosensitive drum, having a surface tension formed with the developing solution, having an electric force generated from a voltage difference between the developing roller and the photosensitive drum, absorbing the developing solution using the surface tension to form an ink film on a surface of the developing roller, and transferring the ink film to the photosensitive drum using the electric force.
