Image forming apparatus

An image forming apparatus comprising:

• a color image former that forms a color image with a plurality of process color toners in different colors;
• a spot color image former that forms a spot color image with a spot color toner in a spot color different from any of the colors of the plurality of process color toners;
• a transfer unit that transfers the formed color image and the formed spot color image onto a recording material;
• a fixing unit that fixes the transferred color image and the transferred spot color image onto the recording material;
• and
• a hardware processor that selects a first mode or a second mode depending on whether or not a type of the recording material and an amount of toner to be attached onto the recording material satisfy a predetermined condition,
• wherein the number of times of image transfer and fixation onto an identical surface of the recording material is two or more predetermined times in the first mode,
• wherein the number of times of image transfer and fixation onto an identical surface of the recording material is less than the predetermined times in the second mode,
• wherein when images are formed on both surfaces of the recording material, the predetermined condition differs between a first surface and a second surface of the recording material.
