Image forming apparatus, image formation control method, and recording medium which stores image control program and is readable by computer

摘要

An image forming apparatus includes an image processing section to process gradation characteristic of the image data based on a tone curve, an image forming section to form an image based on the image data processed by the image processing section; and a control section to control processing in the image processing section. The control section has a function to adjust characteristic of output density relative to input density of image data as the gradation characteristic as a tone curve via a setting screen, saves operational situations at the time of adjustment of the tone curve on the setting screen as a history, and, when the history is designated, reproduces a state at the time of the past adjustment for the tone curve on the setting screen by using the saved operational situations.
