A image forming method is provided to form a high-quality color image having a wrinkle-like texture. A first primer layer 31 is formed by way of discharging first ink, which is photo-curable ink, onto a medium 40 in such a way as to make a perforated coat, and fully hardening the first ink by light irradiation; and a second primer layer 32 is formed by way of discharging second ink onto the medium 40 on which the first primer layer is already formed; and a color ink layer 33 is formed by way of discharging color ink onto the second primer layer.
