An image processing device calculates saturation of each pixel on the basis of multicolor image data; determines a pixel as a chromatic/achromatic pixel based on a threshold value; generates achromatic pixel data for formation of an image using only a color material of black; generates chromatic pixel data constituting a double color image and containing single color image data for formation of an image realized by a combination of color materials; generates for the chromatic pixel, single color image data such that the consumption of a color material of a chromatic color corresponding to the single color increases with increase in the saturation of the chromatic pixel. This makes it possible to generate double color image data by which high contrast and rich tone reproduction can be realized and the boundary between the achromatic region and the chromatic region can be expressed with natural gradation.

An image forming apparatus is provided that is capable of accurately outputting images of both sides of a card type document to the same side of a sheet of paper with a simple operation. On a card size input screen, a first scale for measuring a long-side size of a card type document and a second scale for measuring a short-side size of the card type document are displayed on a same screen such that they intersect at an origin. By operating a long-side size-decreasing instruction portion and a long-side size-increasing instruction portion, the long-side size of the card type document is decreased or increased and inputted. By operating a short-side size-decreasing instruction portion and a short-side size-increasing instruction portion, the short-side size of the card type document is decreased or increased and inputted.

In the case where an output value of a document reading section for at least any of R, G and B is out of a range between a first reference value and a second reference value due to a change in an output value of a reading device caused by an electrical noise, a change of supply voltage, etc. when a document is being read, a second color conversion table is created in accordance with the above change by expanding ranges in a first color conversion table, which ranges are around predetermined first and second reference values and included in regions of RGB color system associated respectively with predetermined tone values of Y, M and C. Using the second color conversion table thus obtained, a color conversion is carried out from the RGB color system into the YMC color system.
