Abstract:
1. An image forming apparatus forming a toner image corresponding to an image signal, comprising: a signal processor which processes the image signal thereby generating a multivalued signal relating to a toner dot to be formed; an image forming unit which forms the toner dot according to the multivalued signal thereby forming the toner image corresponding to the image signal; and a toner-consumption calculator which calculates a toner consumption in the image forming unit based on the multivalued signal, wherein the toner-consumption calculator calculates the toner consumption by integrating values of the multivalued signal and by correcting thus integrated value based on predetermined correction information corresponding to a content of the signal processing of the signal processor, and wherein the signal processor performs tone correction on the multivalued signal according to a gamma characteristic of the image forming apparatus and then outputs the multivalued signal thus corrected.
