PURPOSE:To execute a color development so as to be used for an overhead projector by providing in a sealed-up vessel a means for coating a liquid-like transparent polymer synthetic resin to the surface of a film made of a transparent polymer synthetic resin, which is heated once and whose surface carries an uneven color toner particle group on the surface, and a means for drying said resin after coating. CONSTITUTION:An undeveloped color trumpet copy 45 discharged from a color copying machine is inserted along a guide 46. First of all, a liquid-like transparent polymer synthetic resin like particles is coated to a toner layer side of the copy 45 by a spray 39 until the toner layer is covered completely. As for a necessary coating quantity, there is a difference depending on a trumpet original, therefore, it is controlled to a range exerting no influence on a color developing property by adjusting a carrying speed of the copy 45 or a diameter of a jet nozzle of the spray 39. Subsequently, said resin is fed to a drying part consisting of a heater 42 and a fan 43, the transparent polymer synthetic resin which is like a liquid is stuck onto the copy 45 by evaporating an organic solvent, and thereafter, the copy 45 is discharged to a tray 47. |
