Abstract: An inkjet ink contains an aqueous medium and pigment particles dispersed in the aqueous medium. The pigment particles contain a pigment and a specific resin. The specific resin includes an acid group and a first repeating unit derived from a specific monomer, and has a crosslinking structure derived from a carbodiimide crosslinking agent. The specific resin has a neutralization rate of at least 20% and no greater than 50%. The first repeating unit has a percentage content in the specific resin of at least 1.0% by mass and no greater than 20.0% by mass. The specific monomer has a morpholine structure or a pyrrolidone structure.

Abstract: An inkjet ink contains coloring particles and an aqueous medium. The coloring particles contain a reaction product between a reactive dye and a specific resin having a primary hydroxyl group. The reactive dye may have a chlorotriazinyl group. The specific resin may include a styrene-(meth)acrylic resin, a polyester resin, or a urethane resin.

Abstract: A toner includes toner particles. The toner particles each include a toner core containing a binder resin, a first shell layer covering a surface of the toner core, and a second shell layer partially covering a surface of the first shell layer. The first shell layers include first domains composed of a first thermoplastic resin and second domains composed of a second thermoplastic resin. The first thermoplastic resin has a glass transition point of at least 35° C. and no greater than 66° C. The second thermoplastic resin has a glass transition point of at least 71° C. and no greater than 105° C. The second shell layers contain a third thermoplastic resin that is more hydrophobic than the first thermoplastic resin and the second thermoplastic resin. The third thermoplastic resin has a higher glass transition point than the first thermoplastic resin.
