摘要:
An object of the present invention is to provide a toner having small-sized and potato-shaped particles created from multiple coherent spherical particles for excellent cleaning ability and high image quality, an image-forming method that realizes high image quality using the toner, and the like. To this end, there is provided a toner, which is produced by granulating toner materials as an organic phase comprising at least a binder resin and a colorant in an aqueous medium and has potato-shaped particles created from multiple coherent primary oil droplets of the organic phase in the aqueous medium.

摘要:
A toner including a binder resin including a polyester resin in an amount of from 50 to 100% by weight based on total weight of the binder resin; a colorant; and a resin dispersant selected from the group consisting of modified polyurethane dispersants and combinations of a basic copolymer dispersant with a pigment derivative. A developer including the toner and a carrier. A method for preparing the toner including dissolving or dispersing a toner composition including a modified polyester resin, a colorant, and a resin dispersant in an organic solvent; dispersing the toner composition liquid in an aqueous medium to prepare an emulsion while reacting the modified polyester resin with a compound having an active hydrogen atom; removing the solvent from the emulsion to prepare a toner particle dispersion; and washing and drying the toner particles. An image forming method and apparatus using the toner are also provided.
