There is described a printing method, an image apparatus and a print. A release fluid is provided for use in the printing method, imaging apparatus and print. The release fluid is a blend an amino functional silicone fluid and a non-functional silicone fluid. The amount of the amino functional silicone fluid is from about 10 weight percent to about 90 weight percent of the release fluid. The amount of the non-functional silicone fluid is from about 10 weight percent to about 90 weight percent of the release fluid. The amount of silanol (SiOH) is less than 200 ppm in the release fluid.

An image forming system of an aspect of the present invention includes: a first image forming portion; a second image forming portion connected in series to the first image forming portion; and an assignment determining portion that determines an assignment of image formation of print data to the first image forming portion and the second image forming portion in accordance with contents of the print data. The first image forming portion forms a first image on the continuous sheet on the basis of the assignment determined by the assignment determining portion, and the second image forming portion forms a second image on a region which is different from a region where the first image is formed on the continuous sheet and which overlaps a non-printable region that is a region where the first image forming portion cannot print, on the basis of the assignment determined by the assignment determining portion.

According to an embodiment, an image processing system includes an image forming unit, a decoloring unit, a storage device, an operation panel and a processor. The storage device stores image data of a plurality of printed materials. The processor forms on a sheet an image based on image data in a page range of the printed material received by the operation panel. The processor determines whether or not images of all pages in the page range have been decolored in a predetermined range after the image formation is executed when the formed image is decolored by the decoloring unit.
