されて定着トナー画像が形成される。For example, in electrophotography, a latent image carrier having a photosensitive layer made of a photoconductive material is given an electrostatic charge, and then image exposure causes the surface of the latent image carrier to correspond to the original. An electrostatic latent image is formed, and this electrostatic latent image is developed with toner to form an unfixed toner image. This unfixed toner image is usually transferred to a recording material such as paper and then fixed to form a fixed toner image.

の有彩色の着色剤が含有されて構成される。Recently, however, means for forming color images using color toners has been attracting attention. Such color toners are usually composed of toner particles containing chromatic colorants such as dyes and/or pigments.
しかし、染料および/または顔料等の有彩色の着色剤は
、紫外線照射によりあるいは酸化により劣化しやすくて
耐候性の低いものが多く、そのため以下の問題点がある
。However, many chromatic colorants such as dyes and/or pigments are easily degraded by ultraviolet irradiation or oxidation and have low weather resistance, resulting in the following problems.

な定着が困難である。(1) Conventionally, as a method for fixing an unfixed toner image,
Flash fixing is known, in which toner particles are fixed using light from a flash lamp, but fixing performance varies depending on the type of dye and/or pigment contained in toner particles, making uniform fixing difficult.
(2) トナー粒子中に含有される染料右よび/または

ことができる。Since the heat roller fixing toner of the present invention is fixed by a heat roller, it is possible to obtain a fixed toner image with uniform fixability regardless of the type of dye and/or pigment, and it is possible to obtain a fixed toner image with uniform fixability regardless of the type of dye and/or pigment. Since it contains an inhibitor, when an unfixed toner image is fixed with a heat roller, a film of ultraviolet absorber and/or antioxidant is formed on the surface of the unfixed toner image, and as a result, the dye and/or antioxidant are formed on the surface of the unfixed toner image.
Alternatively, it is possible to effectively prevent pigment deterioration and prevent early fading of a fixed toner image. Therefore, the weatherability requirements required for color toners are considerably relaxed, so that dyes and/or pigments with generally low weatherability can be used without any problem, resulting in a much wider selection range of dyes and/or pigments. It is possible to obtain a fixed toner image that is wide, rich in color, has uniform fixing properties, and can be stored for a long period of time.
以下、本発明の構成を具体的に説明する。 Hereinafter, the configuration of the present invention will be specifically explained.
