Abstract

An image forming apparatus includes a first image forming unit that forms a metallic-color toner image having a metallic color, a second image forming unit that forms a non-metallic-color toner image having a color different from the metallic color, and a transfer unit that transfers the toner images onto a recording material so that the non-metallic-color toner image is superimposed on an upper side of the metallic-color toner image on the recording material.

First claim

What is claimed is:

1. An image forming apparatus comprising:
a first image forming unit that forms a metallic-color toner image by using a metallic-color toner;
a second image forming unit that forms a clear toner image by using a non-metallic-color toner having an average particle diameter relatively smaller than that of the metallic-color toner;
a transfer unit that transfers the toner images onto a recording material so that the clear toner image is superimposed on an upper side of the metallic-color toner image on the recording material when an area of the metallic-color toner image on the recording material is larger than or equal to a predetermined area; and
a fixing unit that fixes the toner images transferred onto the recording material on the recording material.

2. The image forming apparatus according to claim 1 , wherein the second image forming unit forms the clear toner image having a transparent color.

3. The image forming apparatus according to claim 2 , further comprising:
a third image forming unit that forms a colored toner image having any of yellow, magenta, cyan, and black colors,
wherein the transfer unit does not superimpose the clear toner image on a portion of the recording material where the colored toner image is superimposed on the metallic-color toner image.

4. The image forming apparatus according to claim 2 , wherein the transfer unit superimposes the clear toner image on the metallic-color toner image, and
wherein the clear toner image has a shape corresponding to a shape of the metallic-color toner image.

5. A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
forming a metallic-color toner image by using a metallic-color toner;
forming a clear toner image by using a non-metallic-color toner having an average particle diameter relatively smaller than that of the metallic-color toner; and
transferring the toner images on a recording material so that the clear toner image is superimposed on an upper side of the metallic-color toner image on the recording material when an area of the metallic-color toner image on the recording material is larger than or equal to a predetermined area; and
fixing the toner images transferred onto the recording material on the recording material.

6. An image forming apparatus comprising:
a first drum that forms a metallic-color toner image having a metallic color;
a second drum that forms a clear toner image having a color different from the metallic color; and
a roller that transfers the toner images onto a recording material so that the clear toner image is superimposed on an upper side of the metallic-color toner image on the recording material when an area of the metallic-color toner image on the recording material is larger than or equal to a predetermined area.

7. An image forming apparatus comprising:
a first image forming unit that forms a metallic-color toner image by using a metallic-color toner;
a second image forming unit that forms a non-metallic-color toner image by using a non-metallic-color toner having an average particle diameter relatively smaller than that of the metallic-color toner;
a transfer unit that transfers the toner images onto a recording material so that the non-metallic-color toner image is superimposed on an upper side of the metallic-color toner image on the recording material, when an area of the metallic-color toner image on the recording material is larger than or equal to a predetermined area; and
a fixing unit that fixes the toner images transferred onto the recording material on the recording material.
