1. An image forming apparatus, comprising:
an image forming unit which forms a toner image on an image carrier and transfers the formed toner image on a paper; a color conversion process unit to carry out a color conversion process to convert inputted image data to image data of an output color in the image forming unit; and a control unit to make the color conversion process unit carry out a preparatory color conversion process to the inputted image data, to determine whether a pixel value of each pixel constituting image data after the preparatory color conversion process is greater than or equal to a threshold which is predetermined or not, to detect the number of pixels in which the pixel value is greater than or equal to the threshold, to select a color conversion process condition for the color conversion process unit based on the detected number of pixels in which the pixel value is greater than or equal to the threshold, and to make the color conversion process unit carry out an actual color conversion process to the inputted image data according to the selected color conversion process condition. |
