Image Forming Apparatus, Image Forming Method, and Computer Readable Medium Recording a Printing Data Generation Program

摘要

An image forming apparatus that uses a plurality of colorants for image formation and performs the image formation based on bitmap data in which each pixel has a gradation value of each color of the colorants, includes: a correction unit which executes a correction processing of correcting gradation values with respect to at least some pixels in which a gradation value of the colorants other than that of black color is 0 and a gradation value of the colorant of black color is not 0 in the bitmap data, wherein the correction unit executes different processing between a case in which the gradation value of black color of the bitmap data of the pixel that is a processing object is a maximum value and a case in which this gradation value is less than the maximum value.
