<p>PURPOSE:To provide a method of repeatedly using paper capable of quickly and completely peeling toner from paper without damaging the fiber to the surface of the paper by using specific toner. CONSTITUTION:As electrophotographic toner whose maximum value of viscoelasticity (tan delta) in a heating temperature range at the time of heating/ fixing is <=3 is used. The toner of this kind has sufficient elasticity and coaguration force, so that excessive sticking force caused by the inroading of the paper fiber into toner stuck to the paper 10 is not generated at the time of heating/fixing. Therefore, after an aqueous solution including a surfactant is supplied to the paper 10 by a liquid supplying unit 30, the toner is softened by heating from heating rollers 45 and 46 and stuck to the surface of an offset belt 44 and when the toner stuck to the surface of the offset belt 44 is peeled from the paper 10, the toner can be completely removed without damaging the fiber of the surface of the paper 10.</p> |
