Toner includes, as toner particles, first particles and second particles. The first particles each include a first core and a first shell layer covering a surface of the first core. The first core contains a first binder resin and is free from metal stearates. The second particles each include a second core and a second shell layer covering a surface of the second core. The second core contains a metal stearate. The first shell layer and the second shell layer are formed of resins of the same type, respectively. The content of the metal stearate in the second core is 50% by mass or more with respect to the mass of the second core as a whole. The number ratio of the second particles is 5% or more but 25% or less of the total number of the first particles and the second particles.

A toner particle includes a binder resin, a colorant, and a wax. The binder resin includes an amorphous polyester resin and a crystalline polyester resin. The amorphous polyester resin includes, as monomer units, a first monomer having a pendant group, terephthalic acid, and ethylene glycol.

A chemically prepared toner composition made up of a toner particle with a core having a first polymer binder, a monomer free radical polymerization formed core shell styrene acrylic latex having a liquid gel core, a pigment, a wax, and a shell formed around the core including a second polymer binder and method to make the same is disclosed. An optional borax coupling agent can be placed between the outer surface of the core and the shell to assist in the binding of the polymer found in the shell onto the surface of the toner core containing the first polymer.

An electrostatic latent image developing toner includes a plurality of toner particles each including a composite core and a shell layer covering a surface of the composite core. The composite core is a composite of a toner core and a plurality of organic particles each adhering to a surface of the toner core. The shell layer contains a first resin having a glass transition point of at least 50° C. and no greater than 90° C. The organic particles each contain a releasing agent and a second resin having a glass transition point of at least 90° C. and no greater than 110° C.

By controlling the migration to the toner particle surface of the crystalline polyester present in the toner particle, a toner is provided that exhibits an excellent durability in long-term use, a stable charging performance after holding in a high-temperature, high-humidity environment, and an excellent low-temperature fixability, in which the toner having a toner particle that contains an amorphous resin, a crystalline polyester, and a wax, wherein the toner particle includes, at the surface thereof, a coat layer containing a cyclic polyolefin resin.

Provided is a decolorizable toner including a binder resin and colorant particles which contain a color developable compound, a color developing agent, and a decolorizing agent, and have a capsule structure coated with an outer shell, wherein the binder resin is contained in an amount of 60 to 80% by mass with respect to the total amount of the toner components.

Provided is a toner having a toner particle containing a binder resin and a wax, wherein the wax concentrations near the outermost surface of the toner and in the surface layer region below the outermost surface are controlled, so that the wax moves with high efficiency to near the outermost surface during heating.

A method for producing a capsule toner includes preparing core particles; preparing a shell fine particle dispersion liquid having a surface tension of 50 mN/m or more, as measured at 25° C., by dissolving a polyester resin in an organic solvent, thereafter performing neutralization with a neutralizer, and thereafter forming the polyester resin into fine particles; adjusting the surface tension of the shell fine particle dispersion liquid to less than 50 mN/m, as measured at 25° C., by adding a substance that does not include a surfactant to the shell fine particle dispersion liquid; and adhering the shell fine particle dispersion liquid to the surfaces of the core particles. The substance dissolves in or mixes with water and (i) has a vapor pressure equal to or greater than the vapor pressure of water or (ii) has a vapor pressure less than the vapor pressure of water and can be azeotropic with water.

A low melt toner includes a core having a core polystyrene-butyl acrylate resin, a crystalline polyester resin, a pigment present in an amount from about 7% to about 20% by weight of the low melt toner, and a paraffin wax; a ratio of the polystyrene-butyl acrylate resin to crystalline polyester resin is in a range from about 5:1 to about 7:1; and a shell disposed over the core including a shell polystyrene-butyl acrylate resin.
