A direct printing image forming apparatus arranged to provide at least a first printed image of intercepted toner particles within a printable area on a first information carrier in accordance with an image configuration. The first printed image has a print quality being a function of print settings of the image forming apparatus which include at least printing zone geometry, toner delivery system, and electric field characteristics. Thereby, the print settings have been set in such a way that, when the image information descrives a matrix of 8 x 6 pixels each 100 % of a single color selected from yellow (Y), magenta (M), cyan (C) and black (K) and in which pixels of the same color are present in at least 6 rows and in at least 5 columns of the matrix giving the first printed image (IM1) 8 x 6 print blocks (Y, M, C, K) having an area close to 25.4 x 25.4 mm, the difference in optical density between any two measurement positions (MP641, MP822) within the print blocks becomes smaller than 0.7 units when measured by means of Macbeth3 RD914.
