Abstract

An image forming apparatus including a developing portion for developing a image carrier with liquid developer including a toner and a carrier liquid, a transfer portion for transferring the image developed on the image carrier in the developing portion onto a surface of the recording medium, and a recording medium transporting portion for transporting the recording medium onto which the image has been transferred with surface of the recording medium onto which the image has been transferred facing downward, with the upward facing surface being sucked and held by air flow.

Claims

1. An image forming apparatus comprising:

a developing portion that develops an image on an image carrier with a liquid developer including a toner and a carrier liquid;

a transfer portion that transfers the image developed in the developing portion on the image carrier onto a surface of a recording medium; and

a recording medium transporting portion that transports the surface of the recording medium onto which the image has been transferred facing vertically downward with an opposite surface of the recording medium being sucked and held by air flow from the recording medium transporting portion.

2. An image forming apparatus according to claim 1, wherein the carrier liquid is nonvolatile oil.

3. An image forming apparatus according to claim 1, further comprising a fixing portion that fixes the recording medium transported by the recording medium transporting portion.

4. An image forming apparatus according to claim 1, wherein the recording medium transporting portion includes a transporting belt having an air flow hole that allows air to flow therethrough.

5. An image forming apparatus according to claim 1, wherein the transfer portion includes a transfer roller serving as a recording medium gripping member that grips the recording medium.

6. An image forming method comprising:

developing an image on a latent image carrier by using a liquid developer including a toner and a carrier liquid;

transferring the image developed on the latent image carrier to a surface of a recording medium;

transporting the recording medium onto which the image has been transferred, with the surface of the recording medium onto which the image has been transferred facing vertically downward, with an air flow holding an opposite surface of the recording medium; and

fixing the transferred image on the recording medium.

7. An image forming apparatus comprising:

a developing portion that develops an image on an image carrier with a liquid developer including a toner and a carrier liquid;

a transfer portion that transfers the image developed in the developing portion on the image carrier onto a surface of a recording medium;

a recording medium transporting portion that transports the surface of the recording medium onto which the image has been transferred facing vertically downward with an opposite surface of the recording medium being sucked and held by air flow from the recording medium transporting portion; and

a fixing portion that fixes the recording medium transported by the recording medium transporting portion,

wherein the transfer portion includes a transfer roller serving as a recording medium gripping member that grips the recording medium.
