Image forming pretreatment liquid, ink set, and image forming method

Abstract

An image forming pretreatment liquid includes a cationic polymer and/or an organic acid of 0.5% by mass or more and 8% by mass or less relative to a total mass of the image forming pretreatment liquid. When the image forming pretreatment liquid includes the organic acid, a lower limit of a content of the organic acid in the pretreatment liquid is preferably 0.7% by mass or more relative to the total mass of the image forming pretreatment liquid. When the image forming pretreatment liquid includes the cationic polymer, a content of the cationic polymer in the pretreatment liquid is preferably 2% by mass or more and 10% by mass or less relative to a total mass of a nonvolatile content of the image forming pretreatment liquid.
