PURPOSE:To enhance fixability of a toner and offset resistance by using a copolymer of methacrylate and/or acrylate and a vinyl monomer contg. fluorine as a core material in a toner composed of the core material and an outer shell. CONSTITUTION:The resin of the core material is composed essentially of a copolymer of methacrylate and/or acrylate, such as butyl acrylate or decyl methacrylate, and a vinyl monomer contg. fluorine, such as vinyl trifluoroacetate or p-fluorophenyl vinyl ether. A magnetic material and a colorant are dispersed into this resin to form the core material, and coated with the outer shell to obtain a microencapsulated toner. The use of the F-contg. copolymer permits fixability of the toner and offset resistance to be improved. |
