PURPOSE:To provide enough fixing ability and offset resistance of a toner by preparing resin particles in a way that a polimerizable monomer having reactive vinyl group and silicone oil having a reactive vinyl group being reactive to a polymerizable monomer having a reactive vinyl group are polymerized with each other. CONSTITUTION:A polymerizable monomer having a reactive vinyl group is reacted to silicone oil having a reactive vinyl group reactive to the polymerizable monomer. In which case, the reactive vinyl group of the polymerizable monomer is copolymerized with the reactive vinyl group of silicone oil, and in process of polymerization, the silicone oil is prevented from phase-separation from a polymer and being one-sided. The silicone oil is uniformly present in the resin particles of a so prepared toner and fixing ability and offset resistance are improved. A toner having excellent friction electrifying properties can be provided. |
