Image forming system including varnish image forming apparatus

An image forming system comprising:

• an image forming apparatus configured to form a toner image on a first recording material on the basis of first image data for the toner image;
• a fixing device configured to fix the toner image on the first recording material by applying heat and pressure to the first recording material on which the toner image is formed by the image forming apparatus;
• a varnish image forming apparatus configured to form a varnish image on the first recording material, on which the toner image is fixed by the fixing device, on the basis of second image data for the varnish image;
• an image reading portion configured to read the toner image and the varnish image which are formed on the first recording material;
• a first tray and a second tray;
• and
• a controller configured to control the image forming apparatus and the varnish image forming apparatus,
• wherein the controller corrects the first image data depending on first detection image data of the toner image read by the image reading portion, and then depending on the corrected first image data, a toner image is formed on a second recording material subsequent to the first recording material,
• wherein the controller corrects the second image data depending on second detection image data of the varnish image read by the image reading portion, and then depending on the corrected second image data, a varnish image is formed on the second recording material,
• wherein in a case that the controller discriminates that deviation occurs between the toner image and the varnish image, which are formed on the first recording material, on the basis of the first detection image data and the second detection image data which are read by the image reading portion, the controller causes the first recording material to be discharged on the first tray, and
• wherein in a case that the controller discriminates that the deviation does not occur, the controller causes the first recording material to be discharged on the second tray.
