Abstract
As a lubricant present between a transfer belt for transferring a print sheet and a platen plate on a rear side thereof and bringing the both into close contact, a lubricant containing 70 weight % or more of a fatty acid ester solvent with carbon number in a molecule of 20 or more and 34 or less is used so as to reduce sliding between the transfer belt and the platen plate and sliding resistance generated between the transfer belt for transferring the print sheet and an auxiliary plate arranged along this.
