Although many methods are known, as described in Japanese Patent Publication No. 23910 and Japanese Patent Publication No. 43-24748, generally, photoconductive substances are used and various means are used to
An electrical latent image is formed on a photoreceptor, then the latent image is developed using toner, and if necessary, the toner image is transferred to a transfer material such as paper, and then fixed by heat, pressure, solvent vapor, etc. and obtain a copy.

を有する。Among the two-component developing methods, widely used methods include a magnetic brush method using an iron powder carrier and a cascade method using a bead carrier, depending on the type of carrier for transporting the toner. These methods are excellent methods that can obtain good images with relatively stable deviations, but on the other hand, there are common problems associated with two-component developers, such as carrier deterioration and image fluctuations due to fluctuations in the toner and carrier mixing ratio. It has its drawbacks.

As a developing method using a magnetic component developer, there is the MagneDry method that uses conductive toner, but although this is stable for development, it has poor transferability on transfer materials such as plain paper. There is an interlude.

This is an excellent developing method that solves problems such as image fluctuations caused by fluctuations in toner density, but conventional toners are black or dark brown, and although it is effective for obtaining black copies, it is difficult to obtain so-called color toners. For example, even two-color copying was difficult with magnetic-component development.

転写性もそこなわない。In the present invention, the coercive force (Hc) of the magnetic powder is set to 200 Oersted or less because if Hc is too thick, the magnetic poles of the developing sleeve during transportation and during development will adversely affect the fluidity and other properties of the toner. γ-Fe with high
This is because 2O3 increases the long axis/short axis ratio of the magnetic powder, making it difficult to uniformly disperse it in the resin, and the hue of the toner and image deteriorates. In addition, the reason why the particle size is 0.1μ or less is that by uniformly dispersing small particle size magnetic substances in the toner, the magnetic substance content in the toner can be reduced (and the coloring power of the magnetic substance can be weakened). However, the toner as a whole is 4JJ image,
This is to obtain the necessary magnetic force during transportation and to obtain uniform coloring power. In addition, γ-Fe20x itself has a high electrical resistance value and uses a fine magnetic material, so even if it is uniformly dispersed in the toner, the toner resistance will not decrease (
It is possible to obtain the necessary triboelectric potential during development, improving developability,
Transferability is not impaired either.
