IMAGE FORMING DEVICE WITH EXTRA HEATING APPARATUS FOR INCREASING GLOSS Russian patent published in 2010 - IPC G03G15/20 

FIELD: physics.

SUBSTANCE: image forming system has apparatus for forming images using toner of different colours on a recording medium which contains a toner receiving layer, a first apparatus for heating and pressing the image formed by the toner on the recording material, a second apparatus heating the image formed by the toner on the recording material which was already heated and pressed by the said first apparatus. The first image heating apparatus provides granularity of the image formed by the toner in the range 0.5≤R≤4 and gloss of the image formed by the toner in the range 5≤G≤40. The second image heating apparatus provides granularity R of the image formed by the toner which is greater than 4 and gloss G which is not less than 60.

EFFECT: obtaining a high quality image with high gloss, uniform distribution of gloss and higher light resistance and strength of the image owing to provision for granularity R of the image at the first image formation step.
