Abstract:
A toner for developing electrostatic latent images, comprising:a matrix of a first resin selected from the group consisting of polyester resins, polyol resins and mixtures thereof, a plurality of domains of a second resin dispersed in said matrix and containing a wax, wherein said second resin is a mixture of a polyolefin resin, a copolymer of a styrene compound/an acryl compound/an acrylonitrile compound and a graft polymer of a polyolefin resin on which a styrene compound, an acryl compound and an acrylonitrile compound have been grafted, wherein the amount of said wax is 2-15% by weight based on the weight of the toner, wherein said matrix is substantially free of domains of said second resin having a diameter greater than 2.0 &mgr;m, wherein at least one of said domains is present as a surface domain on the outer surface of said toner, wherein said surface domain comprises said wax in the form of wax particles present inside said surface domain, and wherein at least one of said wax particles has a diameter of 0.2 &mgr;m or greater.
