Abstract:
The toner according to the present invention comprises a matrix phase composed of a vinyl resin, and domain phases composed of a non-crystalline polyester resin dispersed in the matrix phase, and a number-average domain diameter of the domain phases composed of the non-crystalline polyester resin is 30 to 150 nm. The toner satisfies relation represented by a specific requirement of the total area of the domain phases present in a surface layer area of the toner particle, and the total area of the domain phases present in areas other than the surface layer area, in a given cross-section of the toner particle.
