Abstract
An image forming method using a thermal transfer, wherein a dye-receptive layer on a transfer film is transferred to a print sheet and then dye layers on a dye transfer film are superposed on the dye-receptive layer and subjected to an image forming operation of a thermal head so that an image is transferred to the dye-receptive layer. In order to transfer the dye-receptive layer to the print sheet uniformly to enable subsequent formation of an excellent dye image, the quantity of thermal energy being applied by the thermal head to the transfer film is decreased with elapse of time. This principle can also be used for transferring a protective layer to the print sheet on which a dye image has been formed.
