PURPOSE: To obtain a distinct image in the case of projecting a toner image formed on a transparent supporting body on a screen, etc., by allowing the transparent supporting body which carries a toner image to pass between a heating roll and a pressuring roll on a specified condition.
CONSTITUTION: The toner image 4 formed on the transparent supporting body 3 by using the toner containing binding resin which has two or more peaks in molecular weight distribution or the toner containing cross-linking polymer and the olefine wax of low molecular weight is allowed to pass between the heating roll 1 provided with a mold-released layer 6 consisting of an elastic body and the pressuring roll 2 at a processing speed which satisfies the condition of an expression I. In the expression I, (x) means the processing speed within 50-150mm/sec, (y) means the surface temperature of the heating roll within 130-200°C, and Mw means the weight average molecular weight of the binding resin. In the case of projecting the color fixed image, which is formed, on the screen by an overhead projector, a light beam from a light source is not scattered and the distinct color image is obtained.
