摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus and image forming method that are capable of reproducing a half tone with high resolution while maintaining process stability.SOLUTION: An image forming apparatus generates a screen set by appropriately combining a first screen group (typically a later-described dot screen) expanding a zone as a gradation value increases on the basis of a first rule, the zone that toner is to be attached to, with a screen group (typically a later-described line screen) expanding a zone as a gradation value increases on the basis of a second rule different from the first rule. The apparatus forms an image containing a half tone using the generated screen set. The apparatus has a function (process variation correction) of correcting a shift of gradation characteristics caused by process variation, the shift occurring after the generation of the screen set.
