PURPOSE:To obtain a toner for pressure fixation providing good images free from drop-out, gro7nd stains, etc. by composing the same essentially of wax such as natural wax, and an ethylenevinyl acetate copolymer as a plasticier, and compounding the same with specific dyes. CONSTITUTION:(A) one or more kinds selected among natural wax, polyethylene wax, microcrystalline wax and amide wax, (B) an ethylene-vinyl acetate copolymer as a plsticizer, and (C) 0.1-10wt% one or more kinds selected among metallic complex salt dyes and org. amine salts of acidic dyes, metallic complex salts of org. amine salts of acidic dyes, amine salts of phthalocyanine sulfonic acids, and salts of acidic dyes and basic dyes are mixed, whereby the intended toner for pressure fixation is obtained. This toner is used as a toner for the case when photoreceptors consisting of winding ''Mylar '' on selenium or cadmium sulfide are used as photoreceptors. |
