An image forming method includes: performing a first gloss processing and a second gloss processing. The first gloss processing includes: heating and pressing a processed body which supports a first toner layer containing at least a clear toner [X] onto a first surface of a recording material, while allowing the first toner layer to be closely adhered to a gloss processing belt; and cooling the same. The second gloss processing includes heating and pressing a processed body which supports a second toner layer containing at least a clear toner [Y] onto a second surface of the recording material, while allowing the second toner layer to be closely adhered to the gloss processing belt; and cooling the same. Here, a storage elastic modulus G′ X (150) at 150° C. of the clear toner [X] is lower than a storage elastic modulus G′ Y (150) at 150° C. of the clear toner [Y].
