Image forming apparatus with first and second gloss modes

An image forming apparatus, comprising:

• an image forming portion configured to form a toner image on a recording material and heat-fix the toner image onto the recording material;
• a re-conveying path configured to re-convey the recording material having a front side, on which the toner image has been formed and heat-fixed by the image forming portion, to the image forming portion so that a toner image is formed and heat-fixed on a back side of the recording material;
• a glossing portion configured to perform a glossing process for increasing glossiness of the toner image formed and heat-fixed by the image forming portion;
• and
• an executing device configured to execute:
• a first gloss mode in which the glossing portion performs the glossing process on the toner image of the recording material re-conveyed, after the toner image is formed and heat-fixed on the front side of the recording material, through the re-conveying path to the image forming portion so as to form a high-gloss toner image;
• and
• a second gloss mode in which the image forming portion forms, without re-conveying a recording material to the re-conveying path, a toner image on the recording material so that a glossiness of the toner image formed in the second gloss mode is lower than a glossiness of a toner image formed in the first gloss mode,
• wherein the glossing portion is provided in the re-conveying path.
