Abstract: An image forming system includes an image forming apparatus, a varnish applying apparatus, an input unit, a first image processing unit, and a second image processing unit. The image forming apparatus forms a toner image on a recording material on the basis of image data obtained by subjecting first image data to data change processing. The varnish applying apparatus forms a varnish image on the recording material on the basis of image data obtained by subjecting second image data to the data change processing.

Abstract: An image forming system includes an image forming unit, a varnish applying unit, a conveying unit, an irradiation unit, and a controller. The controller controls conveyance of a recording material so that a conveying speed of the recording material in a case that varnish is applied to the recording material with a toner image is formed is slower than a conveying speed of the recording material in a case that varnish is applied to the recording material with no toner image. The controller controls irradiation of the varnish with light so that intensity of the light with which the varnish is irradiated in a case that the varnish is applied to the recording material with the toner image is lower than intensity of the light with which the varnish is irradiated in a case that the varnish is applied to the recording material with no toner image.

Abstract: An image forming system includes an image forming apparatus, a varnish applying apparatus, and a controller. A toner image formed on a recording material by the image forming apparatus on the basis of inputted first image data is a first toner image, and an image formed on the recording material by the varnish applying apparatus on the basis of inputted second image data is a varnish image. In a case that the varnish image is to be formed in a non-image region where the first toner image is not formed, before the varnish image is formed, a second toner image is formed with monochromatic toner by the image forming apparatus on a portion of the non-image region where the varnish image is to be formed.

Abstract: An image forming system includes an image forming apparatus, a fixing device, a varnish image forming apparatus, an image reading portion, and a controller. The controller corrects first image data depending on first detection image data of a toner image formed on a first recording material and 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. The controller corrects second image data depending on second detection image data of a 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.
