Abstract:
1. A method of manufacturing an electrophotographic toner comprising the step of: associating, salting out and fusing resin particles and colorant particles in an aqueous medium, a mixture of a polar wax and a non-polar wax being comprised in the resin particles or in the aqueous medium, wherein (i) a toner particle comprises a domain in the toner particle, the domain comprising the polar wax having a first polar group and the non-polar wax; (ii) the resin particle contains a second polar group; (iii) the resin particle is prepared by polymerizing a mixture of polymerizable monomers comprising a radical polymerizable monomer having the second polar group; and (iv) a weight content of the radical polymerizable monomer having the second polar group is in the range of 0.1 to 15% by weight based on a total weight of the mixture of polymerizable monomers, wherein the weight ratio of the polar wax to the non-polar wax is in the range of 1/40 to 40/40.
