Patent ID: 8335012

Claim:
An image forming apparatus comprising: an acquisition unit configured to acquire image data; a generation unit configured to generate a histogram based on a signal value of each pixel in the image data acquired by the acquisition unit; a derivation unit configured to derive the number of pixels matching a specific condition in the histogram generated by the generation unit; a comparison unit configured to compare the number of pixels derived by the derivation unit with a first threshold value and a second threshold value that is greater than the first threshold value; and a selection unit configured to select a fixing processing adjustment mode for increasing a degree of gloss of a print product by adjusting fixing processing if the number of pixels derived by the derivation unit is smaller than the first threshold value and select a transparent toner mode for increasing a degree of gloss of a print product by using a transparent toner if the number of pixels derived by the derivation unit is greater than the second threshold value.
