Abstract (en)
[origin: EP0848304A2] The device for fixing an unfixed toner particle image (42) on a substrate (40) comprises a belt (12) in face-to-face contact with a reaction surface such as a further belt (14) to form an extended contact zone (Z1) therebetween, to define a substrate path extending through the contact zone (Z1) from an entrance (16) to an exit (18). Heating means (20) heat the belt (12) adjacent the entrance (16) to a temperature above the softening point Tg of the toner. Cooling means (24) forcibly cool the belt (12) intermediate the entrance (16) and the exit (18) to a temperature below the softening point Tg of the toner. Means (32, 34) are provided for applying pressure between the belts (12, 14) intermediate the entrance and exit. Second heating means (28) heat the belt (12) adjacent the exit (18) to a temperature above the softening point Tg of said toner. Thereby un-fixed toner images formed on the substrate can be fixed thereto and provided with a desirable level of gloss in one single device. <IMAGE>
