According to the present invention, since the magnetic developer is composed of an organic ferromagnetic resin as a main component and contains a ferromagnetic metal having a size equal to or less than the wavelength of visible light, the magnetic developer can be colored even if it is used. An excellent vividly fixed developer image can be obtained, and recording with excellent color reproducibility can be achieved by superimposing magnetic developer images of different colors. Further, the magnetic developer has a wavelength of visible light or less. Ferromagnetic metals (including metal ions) such as iron, nickel, cobalt, etc. of a single size or alloys
By including the magnetic properties, it is possible to provide a sufficient magnetic attraction force in the direction of the developer holding member, so that the scattering of the developer is small and the agglomeration of the developer particles is avoided, so that faithful development is possible. In addition, since this ferromagnetic metal has a size not larger than the wavelength of visible light, the light transmissivity is not impaired. Therefore, a colorful magnetic developer excellent in chromaticity and chromatic reproducibility. Image recording is possible. Furthermore, the organic ferromagnetic resin is softened by heating and heat-cured at a softening temperature or higher. Since it is carried out at a temperature lower than the temperature, the fixed recorded image has good flexibility, and a sufficiently fixed fixed recorded image can be obtained even by rubbing or folding the recording paper.

The organic ferromagnetic resin used is a condensed polynuclear aromatic (COPNA resin) consisting of a biren-aromatic aldecht system having a triarylmethyl structure, which is disclosed in the Chemical Society of Japan ('89 / Spring) Proceedings 1IKO4, 1IKO7, 1IKO8. Was used to form an unpaired electron structure by a known photodehydration method or discharge method, and an organic ferromagnetic resin was used which was prepared by sufficiently raising the necessary spin. The resin softened at 55-60 degrees Celsius (T 1 = 55-60 degrees) and hardened at 220 degrees Celsius or higher. Red and yellow organic ferromagnetic resins with rich colors were obtained even with a small amount of metal ions (for example, Fe ions). The particles having a particle diameter of about 12 micrometers are the developer holding member 14- having a magnetic field generating means inside thereof.
It was a force that was sufficiently attracted to the surface of 1, 15-1 by magnetic force. When the contained metal ion is a ferromagnetic metal such as Fe ion, the effect of supplementarily increasing the magnetic force acting on the obtained organic ferromagnetic resin particles was obtained.

The thermoplastic resin used was a styrene resin having a softening temperature of about 60 degrees. Curing temperature or thickening temperature T 2 of 10% of the organic magnetic developer made by the thermoplastic resin is mixed in weight ratio per weight of the total resin in the organic ferromagnetic resin was 215 ° to 225 ° C It was Therefore, the fixing temperature T f is set to T 1
It was fixed at 135 ° C. between T 2 and T 2 . When 50% or more by weight of the thermoplastic resin is mixed, the particles having a particle size of about 12 micrometers are sufficiently formed on the surface of the developer holding members 14-1 and 15-1 having the magnetic field generating means therein. It was found that the organic ferromagnetic resin must not be attracted by the magnetic force, and the composition ratio of the organic ferromagnetic resin must be 50% or more based on the weight ratio of the total resin. This is the meaning of the "main component" of the magnetic developer containing an organic ferromagnetic resin as the main component. This is because unlike the conventional magnetic developer, the whole or almost the whole is a ferromagnetic substance and the whole receives a uniform magnetic force, and the magnetic meaning of using the organic ferromagnetic resin is significantly retained. Is also important. This is because even if the particles of the developer are further destroyed and become smaller, the magnetic force depending on the particle size is surely exerted.

Further, when organic ferromagnetic developer images of different colors were overlaid and recorded on a recording paper, a color mixture image excellent in coloring was obtained.
This color was a developer image with rich coloring that could not be obtained with a conventional magnetic developer containing an inorganic magnetic material. It goes without saying that the same applies to a single color developer image.

[Advantages of the Invention] In the present invention, due to the above-described constitution, a vividly fixed developer image having excellent colorability can be obtained even when a magnetic developer is used, and the light transmission is sufficient without being impaired. Since the magnetic attraction is obtained, the coloring property is excellent, the scattering of the developer and the aggregation of the developers do not easily occur, faithful development is possible, and the fixed image has good flexibility. Even if the recording paper is rubbed or the recording paper is broken, a sufficiently fixed fixed recorded image can be obtained.
