The electrophotographic image recording apparatus includes a photoconductive image bearing member, a charging unit, an exposure unit, developing means, a transferring unit suited to superimpose and transfer the plural kinds of toner images obtained by the developing means, and a processing unit adapted to execute halftone processing image data to be sent to the exposure unit, wherein the plural kinds of toners include two kinds of toners of the same hue and differing in density from each other, and the processing unit tone-processes by the use of a screen pattern having different screen angles for the respective toners. In an electrophotographic image recording apparatus for forming an image by the use of a plurality of colorants including two kinds of colorants of substantially the same hue and differing in density from each other, and an image processing apparatus, a higher quality of image is achieved. Tone processing is effected by the use of a screen pattern having different screen angles for the respective toners.
