## Abstract

According to one embodiment, an image forming apparatus includes a display section, an input section, a control section, and an image forming section. The display section displays a printing target image as a preview. The input section receives designation of an area from a user on a preview image displayed by the display section. The control section distinguishes a region of the printing target image such that a part of a region in the designated area is one of color and monochrome and the other part of the region is the other of the color and the monochrome. The image forming section forms the printing target image on a sheet according to the distinction of the color and the monochrome by the control section.

## Claims

### Claim 1

An image forming apparatus comprising:
a display section configured to display a printing target image as a preview;
an input section configured to receive designation of an area from a user on a preview image displayed by the display section;
a control section configured to distinguish a region of the printing target image such that a part of a region in the designated area is one of color and monochrome and the other part of the region is the other of the color and the monochrome; and
an image forming section configured to form the printing target image on a sheet according to the distinction of the color and the monochrome by the control section.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein
the area designated by the user has a rectangular shape, and
the display section displays the area to superimpose the area on the preview image.

### Claim 3 (depends on 1)

The apparatus according to claim 1, wherein
the area designated by the user has a circular shape, and
the display section displays the area to superimpose the area on the preview image.

### Claim 4 (depends on 1)

The apparatus according to claim 1, wherein
the display section displays a plurality of longitudinal and lateral lines, which form squares, to superimpose the lines on the preview image, and
the input section receives designation of an area from the user in a unit of the squares.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein
a singularity of or a plurality of the areas are present and positions and sizes of the areas are specified beforehand,
the display section displays the specified areas to superimpose the areas on the preview image, and
the input section receives selection of any one of the specified areas.

### Claim 6 (depends on 1)

The apparatus according to claim 1, wherein
the area is a closed area designated by a track of handwriting of the user, and
the display section displays the area to superimpose the area on the preview image.

### Claim 7 (depends on 1)

The apparatus according to claim 1, wherein
a plurality of the areas are designated by the user, and
the display section displays the areas to superimpose the areas on the preview image.

### Claim 8 (depends on 1)

The apparatus according to claim 1, wherein
the control section further determines a charge according to a size of the area designated by the user, and
the display section displays the determined charge.

### Claim 9 (depends on 7)

The apparatus according to claim 7, wherein
the control section compares a threshold defined beforehand and a size of the area or a charge, and
if the size or the charge exceeds the threshold, the display section displays a predetermined mark.

### Claim 10

A computer comprising:
a display section configured to display a printing target image as a preview;
an input section configured to receive designation of an area from a user on a preview image displayed by the display section; and
a control section configured to distinguish a region of the printing target image such that a part of a region in the designated area is one of color and monochrome and the other part of the region is the other of the color and the monochrome.
