摘要:
The present invention provides a toner and a developer which includes the toner. The toner is produced in an aqueous medium and includes at least a binding resin, a colorant and a dispersant which disperses the colorant. The binding resin contains 50% by mass to 100% by mass of a polyester resin, and the colorant is a pigment whose surface is given an acid treatment. The acid value of the dispersant is 1 mg KOH/g to 30 mg KOH/g, and the amine value of the dispersant is 1 mg KOH/g to 100 mg KOH/g.
摘要:
The object of the present invention is to provide a toner having a uniform composition of toner materials among toner particles, excelling in charge stability, enabling high-quality images without substantially causing fog and toner scattering, and having a small diameter and a narrow particle size distribution. The present invention also provides an effective production method of the toner, and an image forming method and the like using the toner. For this end, the present invention provides a method for producing a toner in which a dissolved and dispersed solution of toner materials is dispersed as dispersion particles in an aqueous medium containing no organic resin fine particles to prepare an oil droplet-in-water dispersion, and organic resin fine particles are added to the oil droplet-in-water dispersion to thereby granulate a toner in the presence of the organic resin fine particles.
