ABSTRACT:
An electrophotographic toner which can be fixed at a low fixing temperature, causes no practical problem on offsetting-free properties and has excellent fixing strength to a transfer sheet, and a process for the production thereof, the toner containing a binder resin and a colorant as main components and further containing a Fischer-Tropsch wax formed from natural gas and/or a Fischer-Tropsch wax formed from coal and having a melt viscosity, measured at 110.degree. C., of 1.times.10.sup.5 to 1.times.10.sup.6 poise, the process comprising solution-polymrerizing, suspension-polymerizing or emulsion-polymerizing a vinyl-containing monomer in which the Fischer-Tropsch wax formed from natural gas and/or a Fischer-Tropsch wax formed from coal are/is dissolved in advance, to prepare the binder resin.
