近ではエポキシ樹脂が好ましく用いられている。In electrophotographic copying, a heating melt contact method using a heat roll is used as one of the methods for fixing toner images. In recent years, there has been a demand for toner with a low fixing temperature due to the development of home appliances due to the reduction in energy consumption, the increase in copying speeds, and the spread of pull-color copying machines. For this reason, epoxy resins have recently been preferably used as binder resins for toners.

ことができるが、まだ満足できるものではない。Epoxy resins have similar glass transition temperatures compared to conventional styrene-acrylate copolymers, but
Since the melting start temperature is low and the melt viscosity is also low, when an epoxy resin is used as the binder resin, good fixing properties can be obtained at low temperatures. However, with general epoxy resins, an offset phenomenon occurs when they are fixed with a heat roll. Ratio of weight average molecular weight to number average molecular weight Mvr/
Although it is possible to obtain a certain degree of fixing temperature range by using an epoxy resin having a wide molecular weight distribution with Mn of 1.8 to 10.0, it is still not satisfactory.

た。Attempts have also been made to prevent the offset phenomenon by adding substances that have a mold release effect, such as low molecular weight polypropylene, low molecular weight polyethylene, natural wax, paraffin, etc. However, in order to prevent the offset phenomenon,
It is necessary to add large amounts of these substances, which impairs transparency and results in overhead production (
When copied onto an Of(P) film, the light transmittance is reduced, resulting in poor color reproducibility, and the blue color, which involves overlapping colors, has the disadvantage that the colors become dull. As a result of conducting research to eliminate these drawbacks, the present inventors discovered that by using an epoxy resin and a silicon-modified epoxy resin in combination, a wide fixing temperature range can be secured without impairing transparency.

ましい。The silicone-modified epoxy resin used in the present invention is a known one, and can be obtained, for example, by modifying an epoxy resin with a silicone resin. Modification in this case means chemically bonding silicone resin to epoxy resin.
It means changing the properties of epoxy resin. As the silicone resin, one having a functional group that can react with the epoxy resin having a hydroxyl group, such as a hydroxyl group directly bonded to a silicon atom, a halogen atom, an alkoxy group, an acetoxy group, etc., is used. Specific examples include organomethoxypolysiloxane, organosiloxanol polysiloxane, and the like. In this case, the epoxy resin is

The modification of the epoxy resin with the silicone resin is preferably in the range of 10 to 50% by weight. Silicone modified epoxy resin has a melting point of 6

共重合体などを含有していてもよい。The proportion of the silicone-modified epoxy resin in the binder resin of the electrophotographic toner of the present invention is preferably 6 to 40% by weight, particularly 5 to 20% by weight of the epoxy resin as the main resin. If the silicone-modified epoxy resin is less than 6% by weight, it has no effect on fixing properties (and it is difficult to obtain a wide fixing temperature range without impairing transparency. Also, if it is more than 40% by weight, the compatibility with the main resin is poor). The binder resin may contain polyester, styrene-acrylic copolymer, or the like.

A positively chargeable toner having an average particle size of 12 μm was prepared. When 5 parts of this toner was mixed with 100 parts of fluorine-coated iron powder carrier and 20,000 copies were made continuously using a copying machine, clear magenta images could be obtained. Furthermore, in order to evaluate the fixing temperature range, we conducted a fixing test by passing unfixed copies through a Silico/Flor fixing device whose upper roll was coated with silicone oil.
No offset occurred over a wide temperature range of 65° C., and good fixing performance was obtained despite the low temperature range. It also has excellent transparency when copied onto OHP film.

No offset occurred over a wide temperature range of 115 to 165°C (and good fixing properties were obtained despite the low temperature range).

When the mixture was mixed with 100 copies and 20,000 copies were made continuously using a copying machine, clear magenta images were obtained. Furthermore, in order to evaluate the fixing temperature range, we conducted a fixing property test and found that no offset occurred over a wide temperature range of 115 to 165°C, and good fixing properties were obtained despite the low temperature range.

Occurred. Furthermore, in order to evaluate the fixing temperature range, we ran an unfixed copy through a silicon roll fixing device whose upper roll was coated with silicone oil, and conducted a fixability test. Good fixability was obtained, and it was confirmed that there was a problem in practical use.

10 and 2 parts of Bondron P-51 were premixed, heated and melted, kneaded, crushed, and classified to obtain an average particle size of 12 μm.
A positively chargeable toner was prepared. When 5 parts of this toner was mixed with 100 parts of fluorine-coated iron powder carrier and continuously copied using a copying machine, clear images were obtained. However, when we conducted a fusing test to evaluate the fusing temperature range,
Only in the extremely high temperature range of 160 to 220° C., no offset occurred and fixing properties were obtained, but the fixing properties were unsatisfactory at low energy.
