摘要： An ink set includes an inkjet ink and a pretreatment liquid. The inkjet ink contains pigment particles, an anionic dispersant, and binder resin particles. The pigment particles have a major axis of at least 50 nm and no greater than 200 nm. The pigment particles have an aspect ratio of at least 2.0 and no greater than 3.0. The binder resin particles contain a specific binder resin. The specific binder resin has a glass transition point of at least 0° C. and no higher than 45° C. The pretreatment liquid contains water and a cationic material.
