。(IV) However, the brown toner containing these red colorants and yellow colorants has poor fixability to transfer paper in the fixing step in the copying process. Therefore, the toner melted by heating adheres to the heating roller at a distance from the transfer paper, and is accumulated on the thermistor (temperature detection "R") provided on the heating roller, the cleaning blade, etc. This toner transfers to the pressure roller side and adheres to the back side of the transfer paper, causing a back stain (offset) phenomenon.

。As is clear from the Examples and Comparative Examples, when the brown toner of the present invention is used, almost no staining occurs on the back of the transfer paper. In particular, the brown toner containing the compound represented by the formula (II)-a as a yellow colorant does not cause any staining on the back side of the transfer paper even after 10,000 sheets of continuous copying. When copying is performed using conventional brown toner, significant back staining is observed on the transfer paper after 1800 copies have been made.
（発明の効果） 本発明の電子写真用茶色トナーは、このように。(Effect of the invention) The electrophotographic brown toner of the present invention is thus prepared.

提供し得る。Since it has good fixability to transfer paper, it is difficult to peel off from the transfer paper during the copying process. Therefore, there is no possibility that the peeled toner passes through the pressure roller and adheres to the back side of the transfer paper, thereby causing stains on the back side of the transfer paper. As a result, the brown toner of the present invention can provide a clean electrophotographic image on the backside.
