The regulation for the energy consumption of printers and copiers are getting severe year by year. And with the speed up of the machine system, the fusing of toner on the paper gets more difficult. So the toner which can be fused in lower energy is expected. There are still several ways for that problem. To use low Tg and low Tm resin for binder is the typical one for instance, but there is a barrier to improve more by just controlling the Tg and Tm of the resin.In NIP18 the effect of crystalline polyester for low energy fusing was reported; the properties of the toner that contains crystalline polyester, the quantitative effect of crystalline polyester for toner, the effect of the dispersion size of crystalline polyester in toner and the way to disperse the crystalline polyester.In this report, by controlling the kinds of monomers and the reaction hours, various kinds of crystalline polyester are prepared. And the effects of its melting point and molecular weight for the fusing ability and the storage stability of toner are investigated. Also the property of the toner which contains the crystalline polyester with small amount of the monomer which has a long chain is investigated. As the result, one type of crystalline polyester, which is better for toner, is reported.
