  • Patent number: 12282276
    Abstract: An image forming method to be performed by an image forming apparatus includes forming, transferring, fixing, and drying. The forming forms a foil portion to which foil is adhered on one surface of a recording medium. The transferring transfers an image to the one surface of the recording medium after the forming of the foil portion. The fixing fixes the image transferred to the one surface of the recording medium by the transferring of the image, to form a foil image portion including the foil portion and the image on the recording medium. The drying dries the recording medium on which the foil portion is formed, between the forming of the foil portion and the transferring of the image.
