FIXING DEVICE FOR WET COPYING MACHINE

PURPOSE:To completely remove an excess solvent and to obtain satisfactory image quality at the time of high speed conveyance by making longer the time when transfer paper is in contact with plotter rollers or a plotter belt without deteriorating carrying property. CONSTITUTION:The plotter rollers 22 and 22' of a fixing device for a wet copying machine are spaced on a transfer paper feeding path so that the rollers 22 and 22' pair with the backup rollers 23 and 23', respectively. The pair of the rollers 22 and 23 and that of the rollers 22' and 23' are in contact with each other. Since the plotter belt or plural sets of plotter rollers 22 and 22' are arranged upstream of a pressure roller 1 incorporating a fixing heater on the transfer paper feeding path, the time when copying paper is in contact with the plotter rollers 22 and 22' or the plotter belt can be made longer, and accordingly the solvent is completely removed. Higher pressure between the pairing rollers and the formation of a large nip is not needed to achieve excel lent transfer paper carrying properties, and the occurrence of image irregularity is prevented.
