Abstract

An image forming apparatus includes an image forming unit that forms an image on a recording medium by using a developer and an energy generating unit that generates energy that causes the developer on the recording medium, on which the image has been formed by the image forming unit, to generate heat.

First claim

What is claimed is:

1. An image forming apparatus comprising:
an image forming unit configured to form an image on a recording medium by using a developer;
a magnetic flux applying unit configured to apply a magnetic flux to the developer on the recording medium, the magnetic flux causing the developer to generate heat on the recording medium having the formed image; and
a magnetic flux shielding body configured to limit an area of a magnetic field of the magnetic flux, which is applied by the magnetic flux applying unit,
wherein the developer comprises carbon nanotubes as a heat generating material, the carbon nanotubes configured to facilitate fixation of the developer onto the recording medium by generating heat by using the magnetic flux.

2. The image forming apparatus according to claim 1 , further comprising:
a pressing unit configured to press the developer on the recording medium.

3. The image forming apparatus according to claim 1 , wherein the developer is provided on a first side of the recording medium, and
wherein the magnetic flux applying unit is provided on a second side opposite to the first side of the recording medium.

4. The image forming apparatus according to claim 1 ,
wherein the carbon nanotubes are coated with silicon.

5. An image forming apparatus comprising:
an image forming unit configured to form an image on a recording medium by using liquid droplets; and
a magnetic flux applying unit configured to apply a magnetic flux to the developer on the recording medium, the magnetic flux causing the liquid droplets to generate heat on the recording medium having the formed image; and
a magnetic flux shielding body configured to limit an area of a magnetic field of the magnetic flux, which is applied by the magnetic flux applying unit,
wherein the liquid droplets comprise carbon nanotubes as a heat generating material, the carbon nanotubes configured to facilitate drying of the liquid droplets on the recording medium by generating heat by using the magnetic flux.

6. The image forming apparatus according to claim 5 , wherein the liquid droplets are provided on a first side of the recording medium, and
wherein the magnetic flux applying unit is provided on a second side opposite to the first side of the recording medium.

7. The image forming apparatus according to claim 5 ,
wherein the liquid droplets are formed by an ink-jet method.
