Abstract

In an image forming apparatus, a controller performs development of toner patterns corresponding to a first halftoning method and a second halftoning method. One of the toner patterns contains first patch images for the first halftoning method, and another one contains second patch images for the second halftoning method. The controller performs development of only one out of both a first patch image (one of the first patch images) and a second patch image (one of the second patch images) if an absolute value of a difference between the number of dots in the first patch image and that in the second patch image is equal to or less than a predetermined value and an absolute value of a difference between the number of dot-level edges in the first patch image and that in the second patch image is equal to or less than a predetermined value.
